Question

1 ammonia molecule is made up of 1 nitrogen and 3 hydrogen atoms. 1 mole of nitrogen gas contains 6.02 x 10 ammonia So 1 mole of ammonia gas contains _________ hydrogen atoms.

Answer 1

One mole of ammonia gas contains 1.806 x 10^24 hydrogen atoms, which is calculated by multiplying Avogadro's number (6.02 x 10^23) by 3, as each molecule of ammonia contains 3 hydrogen atoms.

Step-by-step explanation:

The student is asking about the number of hydrogen atoms in 1 mole of ammonia gas (NH3). According to Avogadro's number, a mole contains 6.02 x 1023 representative particles. The formula NH3 indicates that for each ammonia molecule, there are 3 hydrogen atoms.

To find the total number of hydrogen atoms in 1 mole of ammonia gas, you use the conversion factor provided by the molecular formula. Here is the calculation:

1 mole NH3 x (6.02 x 1023 molecules NH3/1 mole NH3) x (3 atoms H/1 molecule NH3)

This equals 1.806 x 1024 hydrogen atoms in one mole of ammonia gas.
