Question

What amount of water contains the same number of hydrogen as contained by 68 gram of ammonia?​

Answer 1

Answer:

Explanation:

NOTE: Since it is not specified what 'amount' means, I'm gonna answer in terms of moles. You can then convert it to Litre mL etc.

68g of NH₃ =68/17 = 4 Moles of NH₃. (∵ Molar mass of NH₃ IS 17)

1 Mole of NH₃ contains 3 Moles of H.

∴ 4 Moles of NH₃ contains ( 3×4 ) 12 Moles of H. (Unitary method)

Given that, amount of Hydrogen is same,

∴ 'X' Amount of H₂O contains, 12 Moles of H.

We know 1 Mole of H₂O contains 2 Moles of H

∴ (12/2) 6 Moles of H₂O contains 12 Moles of H. ( Unitary Method)

∴X = 6 Moles.

So, 6 moles of water will contain the same number of Hydrogen as contained by 68 grams of Ammonia.

Hope it helped.
