What is the mass of 8.03 mole of NH3? (NH3 is 17g/mol)
lana [24]

Answer:

the mass of 8.03 mole of NH3 is 136.51 g

Explanation:

The computation of the mass is shown below:

As we know that

Mass = number of moles × molar mass

= 8.03 mol  × 17 g/mol

= 136.51 g

Hence, the mass of 8.03 mole of NH3 is 136.51 g

We simply multiplied the number of moles with the molar mass so that the mass could come

Explain how the solubility of water is useful in maintaining various life processes.
Aneli [31]

Water is called a universal solvent because of its ability to dissolve different types of substances.

The basic unit of life is cell and a large portion of living cell (60%)  is made up of water, this is because cells need water to survive. Biochemical reactions are always ongoing in the living cells and water act as solvents under which these reactions occur. Because of the high solubility of water, it is able to dissolve various substances needed by the body, this makes it easy for the substance to participate in chemical reactions and to move from one point to another.  Without water biochemical reactions will not be able to occur in cells and this will lead to the death of the cells.
