Question

How many moles of each element are present in CH4?

Answer 1

To calculate the moles of each element in methane:

We will use the avogadros number.

For C:

1 mole = 6.022x10^23 atoms

in CH4 there is only 1 carbon.

Which is 1 x 6.022x10^23 atoms = 1 mole

There is 1 moles of carbon.

For H:

For hydrogen its 4 x 6.022x10^23 atoms = 4 moles

therefore there are 4 moles of hydrogen.
