Question

A chemist plans to use 435.0 grams of ammonium nitrate ion a reaction. How many moles of the compound is this?

Answer 1

Ammonium Nitrate has the formula NH4NO3, and has a formula weight of 80.043 grams/mole. We can convert the amount in the problem to moles using this conversion factor. Divide 435 by 80.043 to find the number of moles.

435/80.043 = 5.435

This amount of Ammonium Nitrate contains 5.44 moles of substance, adjusted for significant figures.

Answer 2

The number of mole in 435.0 grams of ammonium nitrate is 5.44 moles

Description of mole

The mole of a substance is related to it's mass and molar mass according to the following equation:

Mole = mass / molar mass

With the above formula, we can obtain the number of mole in the compound.

How to determine the number of mole

• Mass of NH₄NO₃ = 435 g
• Molar mass of NH₄NO₃ = 14 + (4×1) + 14 + (3×16) = 80 g/mol
• Mole of NH₄NO₃ =?

Mole = mass / molar mass

Mole of NH₄NO₃ = 435 / 80

Mole of NH₄NO₃ = 5.44 moles
