Question

what is the number of molecule present in 2 mole CO2?​

Answer 1

Explanation:

1.2044 x 10^24

Which is the same as 12.044 x 10^23, but in proper scientific notation.

Don’t get confused by moles as a number; it is a lot like a dozen. A dozen molecules of CO2 has as many molecules as a dozen molecules of H2O, which has as many molecules as a dozen molecules of N2. Likewise, a mole of CO2 has as many molecules as a mole of H20, which has as many molecules as a mole of N2. The only differences is that a dozen is always 12, and a mole is always 6.022 x 10^23.

How many molecules are in 2 dozen CO2 molecules? You just do 2 x 12.

How many molecules are in 2 moles of CO2? You just do 2 x 6.022 x 10^23

I hope this may help you
