Question

a balloon is filled with 1 mole of helium gas at 100 kpa of pressure and a temperature of 300 k. what is the approximate volume of the balloon?

PLEASE HELPPP!!

Answer 1

Answer:

24.94 L

Explanation:

We are given;

• Moles of Helium, n= 1 mole
• Pressure of the gas, P = 100 kPa
• Temperature of the gas, T = 300 K

We are required to calculate the volume of the balloon

• We are going to use the ideal gas equation;

• According to the ideal gas equation;

PV = nRT , where R is the ideal gas constant, 8.314  L.kPa/mol.K

• Rearranging the formula;

V = nRT ÷ P

  = ( 1 × 8.314 × 300 K) ÷ 100 kPa

  = 24.94 L

Therefore, the volume of the balloon is 24.94 L
