Question

Convert 2.73 g NH4Cl to moles from grams

Answer 1

The mole of NH4Cl is 0.0512 mole

Explanation:

Given parameters

Mass of NH4Cl = 2.73g

The next thing is to find the molar mass of NH4Cl

Given the molar mass of each element

• N = 14 g/mol

,

• H = 1 g/mol

,

• Cl = 35.5 g/mol

NH4Cl = 14 + (4 x 1) + 35.5

NH4Cl = 14 + 4 + 35.5

NH4Cl = 53.3 g/mol

The formula for calculating mole is written below

`\begin{gathered} \text{Mole = }\frac{\text{ reacting mass}}{\text{molar mass}} \\ \text{Mole = }(2.73)/(53.3) \\ \text{Mole = 0.0512 mole} \end{gathered}`

Hence, the mole of NH4Cl is 0.0512 mole
