Answer:

18.94 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 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.
