What is the number of formula units in a 9.87 mol sample of NH4NO3?

59.42 * 10²³ formula units

Explanation:

Given dа ta:

Number of moles of NH4NO3 = 9.87 mol

Number of formula units = ?

Formula:

Number of formula units = moles * Avogadro number

Solution:

Avogadro number = 6.02*10²³

Number of formula units = 9.87 * 6.02 * 10²³

Number of formula units = 59.42 * 10²³ formula units
