To make 100.0 mL of a solution that is 0.20 M in potassium iodate using 0.080 M sulfuric acid as the solvent requires __________ g of KIO3 (molar mass = 214.001 g/mol).
molarity of KIO3 = 0.2M
volume of solution = 100ml = 0.1L
no of moles of KIO3 = molarity * volume in L
= 0.2* 0.1 = 0.02moles
mass of KIO3 = no of moles * gram molar mass
= 0.02*214.001 = 4.28002g >>>>answer
