Answer:
64.15 mL.
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 n and P are constant, and have two different values of V and T:
V₁T₂ = V₂T₁
V₁ = 65.0 mL, T₁ = 92.4°C + 273 = 365.4 K.
V₂ = ??? mL, T₂ = 87.6°C + 273 = 360.6 K.
∴ V₂ = V₁T₂/T₁ = (65.0 mL)(360.6 K)/(365.4 K) = 64.15 mL.
