How many molecules of ch4 are present in .41 moles

6.56g

Explanation:

No of moles = mass given/molar mass

Molar mass of ch4

C is carbon which is 12

H is hydrogen which is 1

Molar mass= 12+4(1)

Molar mass= 16g/moles

No of moles given is 0.41moles

No of moles = mass given/molar mass

Mass given = molar mass × no of moles

Mass given = 16×0.41

Mass= 6.56g

yes it is balanced
