Question

How many atoms are in 0.34 moles
of strontium

Answer 1

I got 0.34 x 6.02 x 10^23 which equals
2.047 x 10^23...............but Im not 100%

Answer 2

`2.04782 * 10^(23)` atoms .

Explanation:

Given : 0.34 moles of strontium.

To find : How many atoms are in 0.34 moles .

Solution : We have given that 0.34 moles

1 mole =
`6.023 * 10^(23)` atoms .

0.34 moles =
`0.34\ *\ 6.023 * 10^(23)` atoms .

0.34 moles =
`2.04782 * 10^(23)` atoms .

Therefore,
`2.04782 * 10^(23)` atoms .
