Question

Convert the mass to moles60.00g NaOH = ____ moles

Answer 1

The mole of NaOH is 1.5 moles

Explanation

Given parameters

Mass of NaOH = 60.0g

To find the mole of NaOH, we need to find the molar mass of NaOH

Given the molar mass of each element

• Na = 23 g/mol

,

• O = 16 g/mol

,

• H = 1 g/mol

Molar mass of NaOH = (23) + (16) + 1

Molar mass of NaOH = 23 + 16 + 1

Molar mass of NaOH = 40 g/mol

The formula for calculating molar mass is given below as

`\begin{gathered} \text{Mole = }\frac{\text{ reacting mass}}{\text{molar mass}} \\ \text{Mole = }(60)/(40) \\ \text{Mole = 1.5 moles} \end{gathered}`

Hence, the mole of NaOH is 1.5 moles
