What mass of solid naoh (97.0 % by mass) is required to prepare 1.00 l of a 10.0% solution of naoh by mass? the density of the 10.0% solution is 1.109 g/ml.

The mass of 97 % of NaOH solution required is 114.33 g

Explanation:

To calculate mass of a substance, we use the equation:

We are given:

Density of 10 % solution = 1.109 g/mL

Volume of 10% solution = 1 L = 1000 mL     (Conversion factor:  1 L = 1000 mL)

Putting values in above equation, we get:

The mass of 10 % solution is 1109 g.

To calculate the mass of concentrated solution, we use the equation:

where,

are the concentration and mass of concentrated solution.

are the concentration and mass of diluted solution.

We are given:

Putting values in above equation, we get:

Hence, the mass of 97 % of NaOH solution required is 114.33 g
