# What is the volume of 2.0 moles of an ideal gas at STP?

1 mole of an ideal gas occupies 22.4 liters at STP - so 2 moles occupies 44.8 liters.

### Explain why the molar volume of a gas at RTP is greater than that of the gas at STP?

At RTP the assumed temperature is 293ºK, at STP the assumed temperature is 273ºK. The formula used for this is Pressure x Volume = moles x ideal gas constant x Temperature. So Volume = (moles x ideal gas constant x temperature) / Pressure Assuming Pressure and moles stays constant... Volume at RTP = ( 1 mole x 8.31451 x 293 K ) / ( 101.325 Pa) Volume at RTP = 24.0429 Volume at RTP =…

### What is the volume of 4.0 moles of an ideal gas at STP?

Because you're in STP conditions, you can use molar volume in a proportion. Molar volume is the volume one mole of an ideal gas will take up at STP: 22.4 liters/mole. To set up a proportion, think: if one mole of a gas occupies 22.4 liters, then 4.0 moles of a gas will occupy x liters. 1 mole/22.4 L = 4.0 mole/X L x = 44.8 liters
