Question

PLEASE HELP! Calculating density given % by mass and molar? Thank you so much!

Sulfuric acid is H2SO4. A sulfuric acid solution is 10.78M and it is 67.0% by mass. Calculate its density.

Answer 1

Please do give a thumbs up.

Answer: Molarity = (% 7 (density) x 10 of south I soution Molar mass of solute) molar mass of H2SO4 = 98.079 g/mol. civen, molarity = 10.78M. %w = 67 Using above formula, density 10.78= 67 * d x 10 980079 d = 10.78 x 98.079 67 x 10 d = 1.578 g ML ANSWER
