What is the molarity of a.) 3.62 mol NaCl in a 400.0 mL solution b.) 0.36 g Na 3 PO 4 ●12H 2 O in a 200.0 mL solution c.) HCl if 130.0 mL water is added to 20.0 mL of a 0.5 M HCl solution STOICHIOMETRY 3.) What mass of Al(OH) 3 is needed to create 6.0 mol of AlCl 3 in: Al(OH) 3 + 3HCl B AlCl 3 + 3H 2 O 4.) How many g CO 2 produced from combustion of 27.4 g of C 6 H 8 in the unbalanced equation: C 6 H 8 + O 2 B CO 2 + H 2 O If 87.6 g CO 2 is actually produced in an experiment, what is the percent yield of CO 2 ? 5.)
