Answer:
1.8 moles
Explanation:
Number of moles = ?
Pressure = 15.4 atm
Volume = 2.92L
Temperature = 32°C = (32 + 273.15)K = 305.15K
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume in which the gas occupies
n = number of moles
R = ideal gas constant = 0.082J/mol.K
T = temperature of the gas
PV = nRT
n = PV / RT
n = (15.4 * 2.92) / (0.082 * 305.15)
n = (44.968 / 25.0223)
n = 1.797 moles = 1.8 moles
Number of moles of the gas is 1.8 moles
