Question

In Part C of the experiment, you will need to prepare 60. mL of a solution that is 0.10 M in sodium hydrogen phosphate heptahydrate (Na2HPO4 · 7 H2O, MW = 268.1 g/mol) and 0.10 M in ascorbic acid (C6H8O6, MW = 176.1 g/mol). (a) How many grams of sodium hydrogen phosphate heptahydrate will you need? Report your answer to three significant figures. g Na2HPO4 · 7 H2O (b) How many grams of ascorbic acid will you need? Report your answer to three significant figures. g ascorbic acid

Step 1

Given: - Volume of solution = 60 mL - Molarity of sodium hydrogen phosphate heptahydrate = 0.10 M - Molar mass of Na2HPO4 · 7 H2O = 268.1 g/mol Convert 60 mL to liters: 60 mL = 60/1000 L = 0.06 L Calculate moles of Na2HPO4 · 7 H2O: Moles = Molarity x Volume (in Show more…
