Question

Conc. Aqueous sulpuric acid is 98%H2SO4 by mass and has density of 1.80 g/ml. Volume of acid required to make 1 litre of 0.1M H2SO4 solution is

Answer 1

By the formula M1 = density × 10 × % by mass / atomic mass
A/c to question ,,
M1 = 98×1.80×10 / 98 =18
Now from formula , M1V1 = M2V2
M1=18, V1=?, M2=0.1, V2=1L
So, V1= M2V2 / M1
V1 =0.1×1 /18 =0.0055
So
Ans is 0.0055liters
