Determine the molar mass of a simple gaseous substance if 5 g takes up a volume of 4 liters. What kind of gas is it? Calculate its hydrogen density.
1 mole of any gas under normal conditions takes a volume of 22.4 liters. Molar mass of gas:
22.4 / 4 * 5 = 28
A simple substance is nitrogen (N2).
Density for hydrogen:
28/2 = 14.
Answer: nitrogen, 14.
