1) How many milliliters of oxygen are required to react completely with 173 mL of C4H10 if the volumes of both gases are measured at the same temperature and pressure?

The reaction is: 2C4H10(g) + 13O2(g) -----> 8CO2(g) + 10H2O(g)

2) At 25.0 ºC and a pressure of 773 torr, a gas was found to have a density of 2.10 g L-1. Calculate its molar mass.

3) What volume in liters does 0.159 g of Cl2 occupy at 19.8 oC and 749 torr?

4) A 1.44 g sample of a gas occupies 1.70 L at 777 torr and 25.0 °C.

What is the formula mass of the unknown gas?

If the gas is an element, which element is it?
