Expert Answer:

Molarity of acid = 3.6;

Molar mass of H2SO4 = 98g


Mass of H2SO4 present in 1 L (1000 mL) of acid = 3.6 x 98 g = 352.8 g


Let’d’ be the density of the acid.


Density = Mass/Volume


Mass of 1000 mL of acid = (d x 1000) g


Percentage of H2SO4 in acid = 29


352.9 x 100/1000 d = 29


352.9/10 d = 29


290 d = 352.9


d = 352.9/290= 1.22 g/mL
