Question

A chemist plans to use 560.0 grams of ammonium nitrate in a reaction. How many moles of the compound is this?

Answer 1

About 7 moles.

Step-by-step explanation:

The molar mass of Ammonium Nitrate is 80.043 grams.

To find moles, we convert grams to moles using a conversion factor.

560g NH4NO3 * 1mol/80.043g

Grams cancel leaving you with your answer in moles which is 6.9962.. basically 7 moles of Ammonium Nitrate.

Hope this helps! Basic conversions are very important in Chemistry.
