Question

A bottle of sulfuric acid (d = 1.787 g/ml) is labelled 86% by mass, calculate molarity of this
solution​

Answer 1

Answer:

A bottle of commercial sulphuric acid (density = 1.787 g mL-1) is labelled as 86 per cent by mass. ... Volume of 100 g of solution=MassDensity=(100g)(1.787 gm L-1)=55.9mL=0.0559L. Molarity of solution (M)=Mass ofH2SO4/Molar massVolume of solution in Litres=(86g)/(98g mol-1)(0.0559L) =15.7 mol L-1=15.7M.

mark me as brainliest.......
