1. Many laboratory gases are sold in steel cylinders with a volume of 43.8 L. If there are x kilograms of argon inside a cylinder whose pressure is 4,592 kPa at 46°C, what the value of x? (1 atm = 101325 Pa)

2. A tank was filled with 18 g of oxygen (O2), 75 g of nitrogen (N2) and 4 g of carbon dioxide(CO2). At 25°C the pressure of the tank was 8.5 atm. If the partial pressure of CO2 in the tank is x atm, what is the value of x?
3. 13 g of an unknown gas in a tank with a volume of 5.53 L has a pressure of 3.83 atm at 28°C. If the molecular weight of the gas is x g/mol, what is the value of x?
4. Ammonia burns in air as follows:
NH3(g) + O2(g) → N2(g) + H2O(g) (unbalanced)
If x liters of N2(g) are formed by burning 9.8 L of ammonia and 9.8 L of oxygen with all species at the same temperature and pressure, what is the value of x?
5. Methane (CH4) at 48°C and 776 mmHg has a density x g/L. What is the value of x?
6. A 3.50 L sample of neon has a pressure of 1.03 atm at 17°C. If the sample has a pressure of 812 mmHg, a volume of x L, and the temperature 138°C, what is the value x?
7. Aluminum metal reacts with hydrochloric acid to produce hydrogen gas.
2 Al (s) + 6 HCl (aq) --> 2 AlCl3 (aq) + 3 H2 (g)
If 2.1 L of H2 was collected over water at 25.0 oC and 694.8 mmHg, x grams of aluminum must have reacted with excess hydrochloric acid. What is the value of x? The partial pressure of water at 25.0 oC is 23.8 mmHg.
