Answer:
V = 267.2 L
Explanation:
Given data:
Volume of balloon = ?
Mass of helium = 2.50 g
Temperature of gas = 180°C
Pressure = 0.87 atm
Solution:
Number of moles of helium:
Number of moles = mass/molar mass
Number of moles = 2.50 g/ 4 g/mol
Number of moles = 0.625 g
Volume of helium:
PV = nRT
R = general gas constant = 0.0821 atm.L/mol.K
0.87 atm× V = 0.625 mol × 0.0821 atm.L/mol.K×453 K
V = 232.45 atm.L /0.87 atm
V = 267.2 L
