Question

You are told that there are 3.7 x 1022 molecules of CH4 in a container. How many

moles of CH4 are in there?

Answer 1

The number of moles can be calculated by dividing the number of molecules by Avogadro's number (6.022 x 10^23 molecules per mole). So, for 3.7 x 10^22 molecules of CH4, we have:

3.7 x 10^22 molecules / 6.022 x 10^23 molecules/mole = (3.7 / 6.022) x 10^-1 moles = 0.612 x 10^-1 moles = 0.612 moles

Therefore, there are approximately 0.612 moles of CH4 in the container
