1. What mass of carbon dioxide (CO2) can be produced from 24.63 g of C6H14 and excess oxygen?
(MM C6H16 =84.18 g/mol, MM CO2 = 44.01 g/mol)
2. If you mix 40.0 mL of a 0.318 M solution of potassium chromate with 40.0 mL of a 0.436 M solution of silver nitrate, what are the masses of all products and reactants after the reaction is complete? Put answers in table form on your paper.
(MM potassium chromate = 194.19 g/mol, MM silver nitrate =169.87 g/mol, MM potassium nitrate = 101.11 g/mol, MM silver chromate = 331.74 g/mol.)
