How many moles of argon are there in 20.0 L at 45°C and 90.8 kPa?

What is the pressure (in atm) of 0.250 mole of nitrogen gas at 18C in a 7.50 x 103 mL container?

If 620 g of ZnS is to be reacted, what volume of oxygen (O2) at 0.877 atm and 34.0°C is needed to carry out this reaction?

2.00L of carbon dioxide gas (the main component of the Martian atmosphere) is contained at a pressure of 101.3 kPa at room temperature (21oC) on Earth. The daytime temperature at the equator during summer on Mars is also 21oC. If the atmospheric pressure on Mars is 6.01 mmHg, what volume would the gas occupy on Mars?

Calculate the volume (in liters) of 0.265 moles of an ideal gas at 585 mmHg and 102oC.

The Haber Process synthesizes ammonia at elevated temperatures and pressures. Suppose you combine 1580 L of nitrogen gas and 4240 L of hydrogen gas at STP, heat the mixture to run the reaction, then separate the ammonia from the reaction mixture. What volume of reactant, measured at STP, is left over? Assume the reaction goes to completion. N₂ (g) + 3 H₂ (g) → 2 NH₃ (g)

What is the mass in grams of Al that were reacted with excess HCl if 5.20 L of hydrogen gas were collected at 5.00 atm and 100. °C in the following reaction? 2 Al (s) + 6 HCl (aq) → 2 AlCl₃ (aq) + 3 H₂ (g)

how many moles of chlorine gas at 120 degrees Celcius and 33.3 atm would occupy a vessel of 16 l?

What volume in liters of fluorine gas is needed to form 863 L of sulfur hexafluoride gas if the following reaction takes place at 2.00 atm and 273.15 K: S(s) + 3F₂(g) → SF₆ (g)?
