H2SO4 solution is 98% by weight of solution with density 1.8gmL−1. Express concentration as percent H2SO4 weight by volume of solution.
MEDIUM
ANSWER
98% by weight of solution means 98g of H2SO4 is present in 100g of solution.
Volume of solution =density of solutionmass of solution=(1.8×1000)g/L100gVolume of solution =181LPer cent H2SO4 w/v of solution = molarity =volume of solution (in L)number of moles of H2SO4Molarity =volume of solutiongiven mass of H2SO4/ molar mass of H2SO4Molarity
