Question

Define morality of a solution air 2 also write it's formula ​

Answer 1

Mortality is defined as the state of the individual being dead. The mortality rate is the death rate of a population which is calculated on the basis of the deaths in the particular region.

The molecular formula for sodium sulphate is Na2SO4.

The molecular formula for water is H2O.

The molecular mass of sodium sulphate is calculated as given below,

M=23×2+32+16×4=142

The number of moles of sodium sulphate in the given question is calculated as,

n=massingramsmolecularweight=15142=0.106

The volume of the solution is 125 ml.

Expressing the above values in terms of litres,

Volume=1251000=0.125

Now, using the formula given above, we calculate the molarity of the given solution.

molarity=numberofmolesofsolutevolumeofsolution

Substituting the values, we get,

molarity=0.1060.125=0.85M

The molarity of the given solution is 0.85M.
