Question 1

At STP, 1 mole of gas has a molar volume of  22.4 L. What is the density (g/L) of oxygen at STP?


Question 2

Baking powder is made up of sodium hydrogen carbonate and calcium hydrogen phosphate. When baking powder is wet, these components react to produce carbon dioxide. The equation for this reaction is given below.
         NaHCO3(aq) + CaHPO4(aq) → NaCaPO4(aq) + CO2(g) + H2O(l)
Assuming all of the carbon dioxide was released as a gas, how many liters of CO2(g) would be formed at room temperature from 4.00 g of NaHCO3 and excess CaHPO4?
