Question
72 g of CaCO3 is treated with 0.500 L of a 1.00M solution of HCl. What volume of CO2 gas, measured at 25˚C and 795. mm Hg can be obtained?
CaCO3(s) + 2HCl(aq) ® CO2(g) + CaCl2(aq) + H2O(l)
Expert Solution
Step 1
Mass of CaCO3 = 72 g
Molar mass of CaCO3 = 100 g/mol
Moles of CaCO3 =72/100 = 0.72 mol
Molarity of HCl = 1.0 M
Volume of HCl = 0.50 L
Moles of HCl = M × V
= 0.50 × 1 = 0.50 mol
