Question

Calculate the number of molecules in 12.7 moles carbon dioxide

Answer 1

Hey there!

There are 6.022 x 10²³ molecules in a mole of CO₂.

We have 12.7 moles of CO₂, so let's multiply 6.022 x 10²³ by 12.7.

12.7 x 6.022 x 10²³

75.6 x 10²³

7.56 x 10²⁴

There are 7.56 x 10²⁴ molecules in 12.7 moles of CO₂.

Hope this helps!
