Question

find the number of atoms in 0.5 mole of C atom​

Answer 1

Explanation:

One mole of carbon contains 6.022×10²³ atoms of carbon. So, 0.5 mol of carbon will contain 6.022×12²³/2 = 3.011×10²³ atoms.

Answer 2

Given,

0.5 mole of C atom

To find,

The number of atoms in 0.5 moles of C atom

Solution,

The number of atoms in 0.5 moles of C atom is 3.011 * 10²³.

1 mole = 6.022 * 10²³ atoms

Avagadro's number = 6.022 * 10²³

No. of moles = 0.5

No of atoms = no of moles * Avagadro's number

                     = 0.5 * 6.022 * 10²³

                    =   3.011 * 10²³

Hence, the number of atoms in 0.5 moles of C atom​ is 3.011 * 10²³.
