1. ### what is the density of 02 at STP?

1 mole. of O2 = 32g. 1 mole. at STP occupies 22.4L. Density = Mass / Volume. Density of O2 at STP = 32g / 22.4L = 1.43g/L = 1.43kg/m³ have a blast!!!

2. ### what is the number of moles in 500L of He gas at STP?

At STP a mole of any gas occupies 22.4 L. So 500L/22.4L/m =22.32m, however 500 has only 1 sig fig so 20 moles is the correct answer

9. ### I did the molar volume lab where you calculate the molar volume of H2 at STP?

AT standard temperature and pressure (STP), the condition should be 0 degree celsius and 1 atmosphere shouldn't it? it's 25 degree celsius for SLC. ps: your title is more like a statement with a question mark at the end than a question.
