What volume in liters of Cl2O gas at STP can be produced from 522 cm3 of chlorine gas at STP and 5.65 g HgO according to the following equation?
2Cl2 + HgO —> HgCl2 + Cl2O (already balanced)

Answer:
Convert everything into moles.
Each mole of gas at STP occupies 22.4 L or 22400 cm^3.
Number of moles of Cl2 = 552/22400 = 0.0246 moles

Molecular mass of HgO = 216.5894 grams/mole
Number of moles of HgO = 5.65/216.5894 = 0.0260

They react in the molar ratio 2:1.
Thus, Cl2 is the limiting reagent. All of it will be reacted. So, number of moles of Cl2O produced is 0.5 times the number of moles of Cl2.

We know that all gases occupy the same volume at constant conditions. So we have the volume of Cl2O = 522 cm^3/2 = 261 cm^3.
