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.) How many moles of AlCl 3 are needed to completely react with the NaOH in 120.0 mL of a 4.2 M NaOH solution in the unbalanced equation: AlCl 3 + NaOH(aq) B Al(OH) 3 + NaCl LIMITNG REACTANT 6.) What mass of CrCl 3 is produced from 32.6 g Cr and 56.0 g Cl 3 in: 2Cr(s) + 3Cl 2 (g) B 2CrCl 3 (s) What mass of excess reactant is left after the reaction completes? 7.) What mass of CaSO 4 is produced if 13.4 g CaCO 3 , 15.0 L O 2 gas, and 10.0 L SO 2 gas are added in a closed system in the unbalanced equation: SO 2 (g) + CaCO 3 (s) + O 2 (g) B CaSO 4 (s) + CO 2 (g) What volume of O 2 gas remains, if any, after the reaction completes?
