Approximately how many moles of Kr⁺ are contained in the laser tube at 0°C and 1 atm?

Consider the reaction:

2 SO₂(g) + O₂(g) → 2 SO₃(g)

a. If 285.5 mL of SO₂ reacts with 158.9 mL of O₂ (both measured at 315 K and 50.0 mmHg), what is the limiting reactant and the theoretical yield of SO₃?

An herbicide is found to contain only C, H, N, and Cl. The complete combustion of a 100.0-mg sample of the herbicide in excess oxygen produces 83.16 mL of CO2 and 73.30 mL of H2O vapor expressed at STP. A separate analysis shows that the sample also contains 16.44 mg of Cl. (b) Calculate its empirical formula.

What is the density of xe gas at stp

Use the molar volume of a gas at STP to calculate the density (in g/l) of nitrogen gas at STP.

At STP, what is the volume occupied by 33.5 g of argon gas?

What is the volume of 3.5 moles of oxygen gas (O₂) at standard temperature and pressure (STP)?
