Dissolved oxygen is very important for the survival of aquatic life. Which of the abiotic factors influence dissolved oxygen?.
The abiotic factors that influence dissolved oxygen include temperature, salinity, and sunlight.
What is an abiotic factor?
An ecosystem can be shaped by abiotic factors, which are non-living components. Examples may be the amount of heat, light, or water in a terrestrial ecosystem. Ocean currents and salinity are examples of abiotic elements in a marine ecosystem. A unique ecosystem is made possible by the interaction of biotic and abiotic elements.Abiotic variables can be made up of substances including water, light, radiation, heat, humidity, atmosphere, acidity, and soil. On the persistence and procreation of species in an ecosystem, these variables have a considerable bearing.Biologic and abiotic elements coexist in ecosystems. Water, soil, and the atmosphere are examples of abiotic factors, which make up an ecosystem but do not contain any live species; biotic factors, on the other hand, include things like bacteria, plants, and animals.To learn more about an abiotic factor refer to:

The mass in grams of 0.700 moles of water (H₂O) = 12.6g/mol (option C)
The mass of a chemical in a mole is known as its molar mass.
It is the total atomic mass of every element that is present in that molecule. The molar mass unit is g/mol.
Determine the molar mass of the water(H₂O):
Molar masses of 1 g/mol of hydrogen and 16 g/mol of oxygen make up a mole.
The chemical formula for water is H₂O.
The water's molar mass is thus:
H₂O = (2 x 1) + 16
= 18 g/mol
Moles of water = 0.700
The molar water (H₂O) mass = 18 g/mol
Object's mass is determined by:
m = (moles of the sample) x (molar mass of the compound)
So, mass of the water (H₂O):

A row of chemical elements makes up a period in the periodic table. The number of electron shells is the same for every atom in a row. Periods are the horizontal divisions or rows in the periodic table, and groups are the vertical divisions or columns.
Periods are shown in the table from top to bottom, numbered 1 through 7. Because they have the same number of orbitals, elements with the same period have identical masses but different characteristics. In other words, the electrons on the same outermost level, which is precisely the number that distinguishes each period, are a characteristic of the elements of a certain period.

How to find partial pressure from mole fraction and total pressure?
To find partial pressure from mole fraction, we have to multiply mole fraction with total pressure in the event.
How to calculate partial pressure using an example?The formula for partial pressure is expressed as Pfraction = molefraction x Ptotal. Partial pressure is the result of multiplying the mole fraction by the total pressure. Let's look at the example below to make it simpler for you to understand:
Consider a chamber with 2.611 atm of pressure, 24.2 g of He, and 4.32 g of O₂. In this instance, we must first get the mole fraction before calculating the partial pressure.
24.2 g Neon x 1 mol Neon / 20.18 g Neon = 1.199 mol Neon
4.32 g Oxygen x 1 mol Oxygen / 31.998 g O₂ = 0.135 mol Oxygen.
Total moles = 1.199 x 0.135 = 1.334 mol gas
Mole fraction Ne = 1.199 mol/1.334 mol = 0.899
Mole fraction O₂ = Oxygen: 0.135/1.334 = .101
Then find the partial pressure
PNe = mole fraction Ne x Ptot = 0.899 x 2.611 atm = 2.35 atm
PO2 = mole fraction O ₂ x Ptot = 0.101 x 2.611 atm = 0.264 atm

If a 10.0 g sample of cobalt -60 is left alone 0.63 g will be left after 21.2 years the half-life of cobaltt-60 is 5.3 years.
What is half life period ?The term half life period is defined as the time required by a radioactive substance to transform into a different substance.
Given :
T = half life of cobalt-60
= 5.3 years
λ = decay constant for cobalt-60 = ?
decay constant is given as follows
λ = 0.693 / T
Substituting the given values
λ = 0.693/5.3

N₀ = initial amount of cobalt-60
= 10 g
t = time of decay
= 21.2 years
N = final amount of cobalt-60 after time "t"
final amount of cobalt-60 after time "t" is given as
N = N₀
Substituting given values
N = 10
N = 10 x 0.0622 g
N = 0.63 g
