Nikolai Chaney · Answer 1

The correct answer is 0, 235 mol

Explanation:

We use the formula PV = nRT. The normal conditions of temperature and pressure are 273K and 1 atm, we use the gas constant = 0, 082 l atm / K mol:

1 atm x 5, 25l = n x 0, 082 l atm / K mol x 273 K

n = 1 atm x 5, 25l / 0, 082 l atm / K mol x 273 K

n = 0, 235 mol
