Stoichiometry Using Molarity Practice Problems
Directions: Answer each question following a chemical equation
H2SO4 + NaOH → Na2SO4 + H2O
★ If 43.2 mL of 0.236 M NaOH reacts with 36.7 mL of H2SO4, what is the
concentration of the H2SO4 solution?
NaOH + HCl → H2O + NaCl
★ If 36.7 mL of HCl solution is needed to react with 43.2 mL of a 0.236 M NaOH,
what is the concentration of the HCl solution?
Al(OH)3 + HCl → AlCl3 + H2O
★ How many mL of 1.2 M HCl is needed to dissolve 5.8 g of Al(OH)3?
H2SO4 + Na2CO3 → Na2SO4 + H2O + CO2
★ Calculate the molarity of the H2SO4 solution if it takes 40.0 mL of H2SO4 to
neutralize 0.364 g of Na2CO3.
Ca(OH)2(s) + HCl(aq) → CaCl2(aq) + H2O(l)
★ How many liters of 0.100 M HCl would be required to react completely with 5.00
grams of calcium hydroxide?
★ If I combined 15.0 grams of calcium hydroxide with 75.0 mL of 0.500 M HCl,
how many grams of calcium chloride would be formed?
