Question

How many moles of electrons are in 24.0g of Carbon-12?

Answer 1

Answer:

2

Explanation:

no. of moles = Given wt. ÷ Molecular wt.

=24÷12

=2

Answer 2

Answer: 24 moles

Explanation:

no of moles of carbon 12 (or just say carbon) in 24.0 g = 2 mol

Now 2 moles of carbon contains 2 x 6.022 x 10^22 atoms of carbon

Each carbon atom contains 12 electrons

Hence total no. of electrons = 12 x (2 x 6.022 x 10^22)

Total no, of e- = 24 x 6.022 x 10^22

Hence no of moles of electrons = 24 moles

The other user has given wrong answer but at least tried, i appreciate

Hope this helps you dear
