Answer:
9.9L
Explanation:
Using the general gas law constant;
PV = nRT
Where;
P = pressure (atm)
V = volume (litres)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question; P = 1.20 atm, V = ?, T = 15°C = 15 + 273 = 288K, n = 0.5mol
Hence, using PV = nRT
V = nRT/P
V = 0.5 × 0.0821 × 288/1.20
V = 11.8224/1.2
V = 9.853
Volume = 9.9L
