How many molecules are contained in 52.5 moles of C2H6?
please explain if you can

3.16x10²⁵ molecules

Explanation:

1 mol refers to the amount of a substance. The amount of C₂H₆ molecules (or any other substance) that are in one mol is given by Avogadro's number:

With that in mind we can calculate how many molecules are there in 52.5 moles:

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
