-
A. 0 C and 2 atm
-
B. STP
-
C. 127 C and 1 atm
-
D. 273 C and 2 atm
Explanation
Maximum molar volume is at 127°C and 1 atm = 32.84 L
T = 127 + 273 = 400 K, P = 1 atm
V = (0.0821 × 400) / 1 = 32.84 L
-
A. 224.14dm³
-
B. 2.24dm³
-
C. None of these
-
D. 22.4dm³
Explanation
Molar mass of CH₄ = 12 (C) + 4×1 (H) = 16 g/mol, so 16 g = 1 mole of CH₄.
At standard temperature and pressure (STP), 1 mole of any gas occupies 22.4 dm³, so CH₄ also occupies 22.4 dm³.
