what is the molecular formula of a compound with the empirical formula of P2O3 and a gram molecular mass of 284 grams?

GalinKa [24]

The answer is: the molecular formula of a compound is P₄O₁₀.

M(P₂O₅) = 2 · Ar(P) + 5 · Ar(O) · g/mol.

M(P₂O₅) = 2 · 31 + 5 · 16 · g/mol.

M(P₂O₅) = 142 g/mol; molar mass of empirical formula.

M(PₓOₙ) = 284 g/mol; molecular mass of unknown compound.

M(PₓOₙ) : M(P₂O₅) = 284 g/mol : 142 g/mol.

M(PₓOₙ) : M(P₂O₅) = 2 : 1.

Calculate the molar mass of butane. Butane's rate of diffusion is 3.8 times slower than that of hleium.

Pie

Answer:

58 g/mol

Explanation:

According to Graham's law, the rate of diffusion of a gas (r) is inversely proportional to the square root of its molar mass (M). Butane's rate of diffusion is 3.8 times slower than that of helium, that is, rButane = rHe/3.8, or rHe/rButane = 3.8. Then,

$\frac{rHe}{rButane} =3.8=\sqrt{\frac{M(Butane)}{M(He)} } =\sqrt{\frac{M(Butane)}{4.00g/mol} } \\M(Butane)=3.8^{2} \times 4.00g/mol\\M(Butane)=58g/mol$
