Answer:
18.94 mL.
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 T are constant, and have two different values of V and P:
P₁V₁ = P₂V₂
P₁ = 9.4 mm Hg, V₁ = 1531.0 mL.
P₂ = 760.0 mm Hg, V₂ = ??? mL.
∴ V₂ = P₁V₁/P₂ = (9.4 mm Hg)(1531.0 mL)/(760.0 mm Hg) = 18.94 mL.
