Under certain conditions, oxygen gas (O2) has a density of 0.00134 g/ml.  Find the volume, in liters, occupied by 250.0 g of O2 under the same conditions.

Gaseous methane CH4 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 7.1 g of methane is mixed with 16.3 g of oxygen. Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.

Assume the density of air at room temperature is 1.2 g/mL. A student is holding two balloons filled with gases; one balloon filled with hydrogen gas (density = 0.082 g/mL) and second balloon filled with carbon dioxide gas (density = 1.9 g/mL). Predict what would happen if the student release both the balloons?

Gaseous ethane CH3CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.90 g of ethane is mixed with 6.65 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Be sure your answer has the correct number of significant digits.
