Question

URGENT!!! NEED HELP!! If the molar mass of Copper is 63.45 g/mol, how many moles are there in 190.35g of Copper?

Answer 1

Answer : The moles of cooper will be, 3 moles

Solution : Given,

Mass of copper = 190.35 g

Molar mass of copper = 63.45 g/mole

Formula used :

`\text{Moles of copper}=\frac{\text{Given mass of copper}}{\text{Molar mass of copper}}`

Now put all the given values in this formula, we get the moles of copper.

`\text{Moles of copper}=(190.35g)/(63.45g/mole)=3moles`

Therefore, the moles of copper will be, 3 moles.
