Question

The oxygen obtained from 72 kg of water is: (A) 72 kg (B) 46 kg (C) 50 kg (D) 64 kg

Tardigrade Admin · Accepted Answer

The oxygen obtained from 72 kg of water is obtained by the following equation. underset overset2(2+16)=362 H 2 O longrightarrow underset overset(2× 16)=322 H 2+ O 2 Therefore, 36 kg of water produce 32 g of oxygen. Hence, 72 kg of water produce oxygen =(32 × 72/36)=64 kg

Q. The oxygen obtained from $72 k g$ of water is:

72 kg

46 kg

50 kg

64 kg

The oxygen obtained from $72 k g$ of water is obtained by the following equation.
$= 36 2 (2 + 16) 2 H_{2} O ⟶ = 32 (2 \times 16) 2 H_{2} + O_{2}$
Therefore, $36 k g$ of water produce $32 g$ of oxygen.
Hence, $72 k g$ of water produce oxygen
$= \frac{32 \times 72}{36} = 64 k g$
