Answer:

V = 44.83 L

Explanation:

Given data:

Mass of fluorine = 76 g

Temperature = 0°C

Pressure = 101.3 Kpa

Volume of fluorine = ?

Solution:

Temperature = 0°C (0°C + 273 = 273 K)

Pressure = 101.3 Kpa ( 101.3 / 101 = 1 atm)

First of all we will calculate the number of moles.

Number of moles of F = Mass/ molar mass

Number of moles = 76 g/ 38 g/mol

Number of moles = 2 mol

Volume of fluorine:

Formula

PV = nRT

V = nRT/ P

V = 2 mol × 0.0821 atm. L/ mol. k × 273 k / 1 atm

V = 44.83 L. atm / 1 atm

V = 44.83 L
