Answer:
492.3 cm³.
Step-by-step explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If P and n are constant, and have different values of T and V:
(V₁T₂) = (V₂T₁).
V₁ = 417.0 cm³, T₁ = 65°C + 273 = 338 K.
V₂ = ??? cm³, T₂ = 126°C + 273 = 399 K.
∴ V₂ = (V₁T₂)/(T₁) = (417.0 cm³)(399 K)/(338 K) = 492.3 cm³.
