Explanation:
Answer:
47.34L
Explanation:
Using the general gas equation as follows:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question,
V = ?
P = 75.2 kPa = 75.2 × 0.00987 = 0.74atm
T = 63°C = 63 + 273 = 336K
n = 1.27mol
Using PV = nRT
V = nRT/P
V = 1.27 × 0.0821 × 336 ÷ 0.74
V = 35.034 ÷ 0.74
V = 47.34L
