Answer 1

Answer:

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.

Explanation:

Mass of solution = M

Mass percentage of the solution of lime = 15%

Mass of lime or calcium hydroxide = m = 30 g

The Formula of mass percentage is given as :

$m/m\%=\frac{m}{M}\times 100$

On substituting the values in ab above formula :

$15\%=\frac{30 g}{M}\times 100$

$M=\frac{30 g}{15}\times 100=200 g$

200 grams is the mass of 15% of the solution of lime that is formed by dissolving 30g of calcium hydroxide in water.
