6.023*x10^21 electrons are present n a given amount of ammonium (NH3).How much amount of hydrogen is required to produce the sample of ammonia
To find out how much hydrogen is required to produce a given amount of ammonia (NH3), we need to use the chemical equation for the reaction between hydrogen gas (H2) and nitrogen gas (N2) to form ammonia:
N2 + 3H2 → 2NH3
According to the balanced equation, 3 moles of hydrogen (H2) are required to produce 2 moles of ammonia (NH3).
Here's how we can calculate the amount of hydrogen needed:
1. Determine the number of moles of ammonia present:
Given: 6.023 x 10^21 electrons
To convert to moles, we need to use Avogadro's number (6.022 x 10^23 entities per mole).
Moles of NH3 = (6.023 x 10^21 electrons) / (6.022 x 10^23 electrons per mole)
= 0.01 moles
2. Calculate the moles of hydrogen required:
According to the balanced equation, 2 moles of ammonia require 3 moles of hydrogen.
Moles of H2 = (0.01 moles of NH3) x (3 moles of H2 / 2 moles of NH3)
≈ 0.015 moles of H2
3. Convert moles of hydrogen to grams:
The molar mass of hydrogen (H2) is approximately 2 grams/mol.
Mass of H2 = (0.015 moles of H2) x (2 grams/mole)
= 0.03 grams of H2
Therefore, approximately 0.03 grams of hydrogen is required to produce the given amount of ammonia (NH3).
