    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.
