Answer to Question #166528 in General Chemistry for Jacob

Question

What is the empirical formula and what is the molecular formula for a substance consisting of 24.44% Ca, 17.06% N and 58.50% O and has a molar mass of 164.10 g/mol

Answer 1

Empirical Formula CaN₂O₆

(CaN₂O₆) n=164.10

(40 + 14*2 + 16*6) =164.10

164n=164.10

n=164.10/164

n=1

Molecular Formula= (CaN₂O₆)1= CaN₂O₆

Therefore, Empirical Formula= CaN₂O₆
