Answer:
Molecular formula = P₄O₁₀
Explanation:
Given data:
Empirical formula = P₂O₅
Gram molecular mass = 284 g/mol
Molecular formula = ?
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 2 ×31 + 5× 16 = 142
n = 284 / 142
n = 2
Molecular formula = n (empirical formula)
Molecular formula =2 (P₂O₅)
Molecular formula = P₄O₁₀
