Question

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

Answer 1

59.42 ×10²³ formula units

Step-by-step explanation:

Given data:

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
