# How many moles of gas are in a volume of 63.3 L at STP?

##### 1 Answer

At STP of 273.15 K and 100 kPa, 63.3 L of an ideal gas would contain 2.33 moles.

At STP of 273.15 K and 1 atm, 63.3 L of an ideal gas would contain 2.82 moles.

#### Explanation:

At STP of 273.15 K

In order to answer this question, divide the given volume by the molar volume of 27.710980 L/mol.
