Question

calculate the mass of sulphuric acid present in 100ml. of 15 percent mass by mass solution of sulphuric acid.(density=1.10g/ml)

Answer 1

Mass of the solution = volume * density = 100 ml * 1.10 g/ml 
      = 110 gms

Mass of sulfuric acid: 15% of 110 gms =  16.5 gms

Answer 2

Answer: The mass of sulfuric acid present in 100 mL is 16.5 grams.

Explanation:

We are given:

Density of solution = 1.10 g/mL

Mass % of sulfuric acid = 15 %

This means that 15 grams of sulfuric acid is present in 100 grams of solution.

To calculate the volume of solution, we use the equation:

$Density=\frac{Mass}{Volume}$

Putting values in above equation, we get:

$1.10g/mL=\frac{15g}{\text{Volume of solution}}\\\\\text{Volume of solution}=90.90mL$

By applying unitary method, we get:

In 90.90 mL of solution, 15 grams of sulfuric acid is present.

So, in 100 mL of solution, the amount of sulfuric acid present will be = $\frac{15g}{90.90mL}\times 100mL=16.5g$

Hence, the mass of sulfuric acid present in 100 mL is 16.5 grams.
