Question

How many moles are present in 2.45 x 1023 molecules of ch4

Answer 1

Approximately 0.406 moles are present in 2.45 x 10^23 molecules of CH4.

Step-by-step explanation:

To find the number of moles present in 2.45 x 10^23 molecules of CH4, we need to use Avogadro's number. Avogadro's number is equal to 6.022 x 10^23 molecules per mole. So, to calculate the number of moles, we divide the given number of molecules by Avogadro's number:

Moles = 2.45 x 10^23 molecules / (6.022 x 10^23 molecules/mol)

Moles = 0.406 moles

Therefore, there are approximately 0.406 moles present in 2.45 x 10^23 molecules of CH4.
