Question

how many moles of atom are contained in 32.7 g of zinc ​

Answer 1

Answer:

Moles =Weight in grams/  molar mass  

​ =32.7/65

       =0.50

Explanation:

Answer 2

Answer:

The number of moles of atoms in $32.7g$ of zinc measured is $0.5mol$.

Explanation:

Data given,

The mass of zinc, m = $32.7g$

The number of moles of atoms in $32.7g$ of zinc, n =?

As we know,

• The molar mass of zinc, M = $65g$

Now,

• The number of moles = $\frac{Given mass}{Molar mass}$
• The number of moles = $\frac{32.7}{65}$
• The number of moles = $0.5$ mol

Hence, the number of moles of atoms in $32.7g$ of zinc, n = $0.5mol$.
