How to calculate number of moles?

The number of moles of a gas at STP can be calculated using the following formula:

PV = nRT

Where;

• P = pressure
• V = volume
• n = number of moles
• R = gas law constant
• T = temperature

At STP, the following applies:

• T = 273K
• P = 1 atm
• R = 0.0821 Latm/molK

1 × 39 = n × 0.0821 × 273

39 = 22.41n

n = 1.74mol

Therefore, the number of moles contained in 39 L of F2 gas at STP is 1.74mol.
