The volume in deciliters of 100 drops of medicine is calculated as 1.77 deciliter.
What do you understand by the term deciliter?Deciliter is a metric unit of capacity which is equal to ¹/₁₀ liter.
Some medical tests report result in grams (g) per deciliter (dL). Gram is equal to the weight of one milliliter or 16 drops of water which is around 1/30 of an ounce. Deciliter measures fluid volume equal to 1/10 of liter. A liter is a little bigger than quart of a fluid.
Given 1drop of medicine =1.77 ml
So, 100drops=177 ml
As, 1ml=0.01 dl
Hence, 177 ml=1.77 deciliter.

Describe how to prepare 500ml of a approximately 0.20 mole of soduim hydroxide (NaOH) using solid sodium chloride
Answer:
To prepare 500ml of a approximately 0.20 mole of soduim hydroxide (NaOH) using solid sodium chloride, you will need to:
Obtain the necessary materials: 500ml of distilled water, 0.20 moles of solid sodium chloride (NaCl) and a container.
Slowly add the solid sodium chloride to the distilled water while stirring the solution.
Use a thermometer to monitor the temperature and stop adding the solid sodium chloride when the temperature reaches 90-100 °C.
The solution will become cloudy and will start to release heat. Allow it to cool down, and then measure the final volume of the solution.
The obtained solution will be a approximately 0.20M of sodium hydroxide.
Please note that this method is called "precipitation method" and it is not the only method to prepare sodium hydroxide solution, and also this method is not safe to handle and should only be done by trained person with proper lab equipment and safety measures.

You have 100 mL of a 6 M solution of NaCI and you need to dilute it to 400 mL. What is the molarity of the new solution?
Answer: 1.5 M
Explanation:
In order to find the molarity of the new solution, we need to use the formula M1V1 = M2V2, where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.
Given that the initial volume is 100 mL and the initial molarity is 6 M, we can plug in the values and solve for M2:
6 M x 100 mL = M2 x 400 mL
M2 = (6 M x 100 mL) / 400 mL
M2 = 1.5 M
So the new solution will have a molarity of 1.5 M.

4. Compare the conductivity observations of dilute and concentrated NiCl₂ and NaOH.
Explain why you observed this.
NiCl₂ and NaOH are both electrolytes, which means that they dissociate in water to form ions, which are charged particles that can conduct electricity.
When NiCl₂ is dissolved in water, it dissociates into Ni²⁺ ions and Cl⁻ ions. The conductivity of a dilute solution of NiCl₂ is relatively low because there are fewer ions present in the solution, and thus fewer ions available to conduct electricity.
When the concentration of NiCl₂ is increased, the conductivity of the solution also increases. This is because as the concentration of the solution increases, there are more ions present in the solution, which results in a greater ability to conduct electricity.
Similarly, when NaOH is dissolved in water, it dissociates into Na⁺ ions and OH⁻ ions. As with NiCl₂, the conductivity of a dilute solution of NaOH is relatively low because there are fewer ions present in the solution. As the concentration of NaOH is increased, the conductivity of the solution increases because there are more ions present in the solution.
In summary, the conductivity of dilute solutions of NiCl₂ and NaOH is low because there are fewer ions present in the solution. As the concentration of these solutions increases, the conductivity increases because there are more ions present in the solution.

O bulb 1 2HI(g) =H2(g) +12(g) The following experiment was devised to determine the equilibrium constant of the reaction O bulb 2 O bulb 3 HI(g) is introduced into five identical 400-cm' glass bulbs, and the five bulbs are maintained at 623 K.The amount of Iz produced over time is measured by opening each bulb and titrating the contents with 0.0150 M Na2S2O3(aq). The reaction of I, with the titrant is O bulb 4 O bulb 5 12 +2Na2S2O3-Na2S406 + 2NaI Submit Previous Answers Correct You have enough information to calculate the value of Q at each time increme Part B What is the value of Kc for the decomposition of HI at 623 K? Express your answer numerically. View Available Hint(s) EVO AE ? Kc =
Methane and ethane, two saturated light paraffins that are gaseous in an atmosphere, make up the majority of the hydrocarbon mixture that makes up natural gas.
What is gases?The percentages of nitrogen, oxygen, argon and other gases in the atmosphere of the Earth are roughly 78%, 21%, 0.9 percent, and 0.1%, respectively. Other gases that make up the final 0.1 percent include trace amounts of carbon dioxide, methane, water vapor, and neon. Gases are substances that can exist as a gas in one atmosphere of pressure. The 11 gases are Nitrogen, Hydrogen, Chlorine, Fluorine, Argon, Neon, Krypton, Radon, Xenon, and Oxygen. Given that they are all elements, these are known as pure gases.
Here,
The majority of the hydrocarbon mixture that makes up natural gas is made up of methane and ethane, two saturated light paraffins that are gaseous in an atmosphere.
