Question

copper is a metal known since ancient times and is used in electricles cables ,how many gram are there in 0.352 mole of copper.[atomic mass of copper=63.5

Answer 1

atomic mass of copper= 63.5u

molar mass of copper =63.5g [M]

molar value given= 0.352[n]

mass = molar mass*number of moles

=> m = M*n

=> 63.5*0.352

=> 22.352g

Answer 2

Answer:

The mass of the copper present in $0.352 mol$ of copper is $22.35g$.

Explanation:

Data given,

• The number of moles of copper, n = $0.352 mol$

• The atomic mass of copper = $63.5u$

Therefore,

• The molar mass of copper, M = $63.5 g/mol$

• The mass of the copper, m =?

Now, we can calculate the mass of the copper by using the equation of the number of moles.

As we know,

• $n = \frac{m}{M}$

Here,

• n = The number of moles
• m = Mass
• M = The molar mass

After putting the given values in the equation, we get:

• $0.352 = \frac{m}{63.5}$
• m = $22.35g$

Hence, the mass of the copper, m = $22.35g$.
