Question

calculate the molarity of 90%(w/v) H2So4 having density of 1.98 g/ml.​

Answer 1

Answer:

Expert Answer:

Mass of solute in 100ml of solution = 90 g of H2SO4

Moles = Mass of solute in 100ml in solution = 90 = 0.9183. Molar mass 98.

Volume = mass X density.

Wt of 100ml of solution = 100 X 1.8 = 180 g.

Solution = solvent + solute.

180= x + 90.

x = 180 -90 = 90 g.

Molarity = No.
