Question

The atomic mass of copper metal is 63.6 amu . Calculate the mass of 3.5 moles of copper.

Answer 1

Answer:

The mass of the copper metal is $222.6g$.

Explanation:

The atomic mass of copper metal = $63.6amu$

Therefore,

The molar mass of copper metal = $63.6g/mol$

The number of moles of copper = $3.5 moles$

The mass of the copper metal =?

As we know,

• The number of moles = $\frac{Mass}{Molar mass}$

Therefore,

• The mass of copper metal = number of moles × molar mass of copper

After putting the given values, we get:

• The mass of copper metal = $63.6\times 3.5$ = $222.6g$.

Answer 2

Answer:

The mass of the copper metal is $222.6g$ .

Explanation:

The atomic mass of copper metal =$63.6amu$

Therefore,

The molar mass of copper metal = $63.6g/mol$

The number of moles of copper = $3.5moles$

The mass of the copper metal =?

As we know,

The number of moles = $\frac{Mass}{Molarmass}$

Therefore,

The mass of copper metal = number of moles $\times$ molar mass of copper

After putting the given values, we get:

The mass of copper metal =  $63.6 \times 3.5 =222.6g$
