Answer:

4.5 atm

Explanation:

We are given;

  • Volume of the cylinder as 20 L
  • Moles of the gas as 4 moles
  • Temperature of the gas as 274 K
  • Universal gas constant as 0.08206 L-atm/mol-K

We are required to determine the pressure in the cylinder.

  • We are going to use the ideal gas equation;
  • According to the ideal gas equation;

PV = nRT

Rearranging the formula;

P = nRT ÷ V

Replacing the values of the known variables;

P = (4 mol × 0.08206 L-atm/mol-K × 274 K) ÷ 20 L

  = 4.497 atm

  = 4.50 atm

Therefore, the pressure in the cylinder is 4.5 atm
