Answer: 41.46 L

Explanation:

La ecuación que describe  relación entre presión, volumen,  temperatura y la cantidad (en moles)

de un gas ideal es:   PV = nRT

Donde:  P = Presión absoluta ,  V= Volumen  , n = Moles de gas , R = Constante universal de los gases ideales,  T = Temperatura absoluta,

R = 0.082 L. atm/mol. °K

V = nRT/P

Calculanting n

n = mass/ molecular mass

n = 4 g / 2g. mol⁻¹

n = 2 mol

T =25⁰ + 273 ⁰K = 298 ⁰K

V = (2 mol ₓ0.082 L. atm / mol.°K x 298 ⁰K) / 1.18 atm = 41.46 L
