If a 1.065 g sample of magnesium oxide of 84.736% were treated with 50 mL of 1.017 N sulfuric acid, what volume of 1.103 N sodium hydroxide would be required in the back titration? In solving, always put a decimal point for values less that 1, example, if your answer is .25, write it as 0.250; add trailering zeroes to the third decimal place if necessary, example, if your answer is 62.7, write it as 62.700, 37.12 write it as 37.120, 123 write it as 123.000) 1. What is the unknown volume (mL) in the problem?
