Answer:
Water volume produced is 7.3 mL
Explanation:
This the reaction:
4NH₃ (g) + 5O₂ (g) → 4NO (g) + 6H₂O (g)
We have to work with density, to solve this question
Density of ammonia = Ammonia mass / Ammonia volume
0,00073 g/mL = Ammonia mass / 6300 mL
(Notice, we had to convert 6.3L to mL)
0.00073 g/mL . 6300 mL = Ammonia mass → 4.599 g
Mass / Molar mass = Mol
4.599 g / 17g/m = 0.270 mole
Ratio is 4:6
4 mole of ammonia produce 6 mole of water
0.270 mole produce (0.270 .6)/4 = 0.405 mol
Molar mass . mole = mass
18 g/m . 0.405 m = 7.30 g
Water density = 1 g/mL
Water density = Water mass / Water Volume
1g/mL = 7.30 g / Water volume
Water volume = 7.3 mL
