does the law of conservation of mass apply to atomic mass

just stuck on this question:
carbon dioxide reacts with calcium hydroxide as shown by the equation:
Ca(OH)2(aq) + CO2(g) -> CaCO3(s) + H2O(l)
A solution containing 0.1 mole of calcium hydroxide reacts with excess carbon dioxide at 298K and at 100kPa.
Which statement is correct?
a) It consumes 4.4L of carbon dioxide gas
b) It produces 24.5 L of liquid water
c) It consumes 0.50 mole of carbon dioxide
d) It produces 10.0 g of solid calcium carbonate

Yes, conservation of mass (or rather, energy) is a universal law.
