Derive the formula of an acid, if it is known that its composition includes acids: 2.13% H- hydrogen 29.79% N- nitrogen 68.08% O- oxygen
The compound formula can be found by the ratio of its constituent elements. To do this, use the formula w (H) / M (H): w (N) / M (N): w (O) / M (O) = H: N: O =>
H: N: O = 2.13: 2.13: 4.26 =>
H: N: O = 1: 1: 2. Then the acid formula is HNO2
