Question

A sample of copper metal has a mass of 848 grams. How many moles of copper are in the sample? 13.34 mol Cu, 13.3 mol Cu, 12.9 mol Cu

Answer 1

`mol_(Cu)=13.34molCu`

Step-by-step explanation:

Hello,

In this case, as the atomic mass of coppe is 63.546 g/mol, with the given mass with can compute the moles as shown below:

`mol_(Cu)=848gCu*(1molCu)/(63.546 gCu) \\\\mol_(Cu)=13.34molCu`

Best regards.
