How many moles are at STP?

Sagot :

No. of moles at STP = Volume at STP (litres) / Molar volume at STP (litres)

The temperature of 273 K and pressure of 1 atmosphere are known as standard temperature and pressure. At STP, one mole of any gas will have a volume of 22.4 L. This volume is known as molar volume of a gas at STP. The formula to find out the number of moles at STP is

No. of moles at STP = Volume at STP (litres) / Molar volume at STP (litres)

Example: How many moles are in 224mL of CO2 at STP?

Standard volume=22.4 L

It means that 1 mole of any atom, molecule or ion occupies 22.4 L of volume at STP (Standard Temperature and Pressure)

1 mole of CO2 = 22.4 L

Given volume = 224 mL = .224 L ( 1 L = 1000 mL)

No. of moles in .224 L = Given volume/Standard volume

= .224/22.4 = 0.01 mole
