Question

Concentrated aqueous sulphuric acid is 98% H2SO4 by mass and has density 1.84g/ml volume of acid required to make one litre of 0.5M H2SO4 solutions

Answer 1

Answer: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 0.0055
