convert to moles and then to grams

Answer 2

Remember what I said Grams-Moles-Atoms

Answer 3

So you will start at Atoms, then get Moles, than Gram

Answer 4

*CH4

Answer 5

CH4 mass= 32.04amu C=12.01,H=1.004*4

1.) 9.3*10^24CH4atoms * 1mole
6.022*10^23atoms
=15.4434molesCH4
2.) 15.4434molesCH4*32.04 grams
1mole
= 494.81gramsCH4

Answer 6

Grams-moles-Atoms
