How many molecules of CH4 are in 48.2 of this compound?

Answer 1

48.2/ 16g = 3.01 * 6.022x10^24= 1.81*10^24

Answer 2

!^g has one mole in it.So answer is equal to avagadro number. 6.02 × 10 23

Answer 3

Divide 32 by molecular mass.Then multiply by avagadro number.

Answer 4

First divide 48.2 by molecular mass.Then get the answer by multiplying it by 6.02 × 10 23

Answer 5

482 grams of CH4 is equivalent to 30,12 moles.

Answer 6

Molar mass of methane, CH4 is 12.0 + 4.0 = 16.0 g/mole482 g x 1 mole/16.0 g = 30.1 moles CH4 (to 3 significant figures)

Answer 7

28

Answer 8

1.81x1024
