How many molecules are there in 0.021 moles of methane?

we know there are 6.023 × 10^23 molecules in one mole of CH4. To find how many molecules are present in 5.8 moles of CH4, all we have to do it multiply Avogadro's number by 2.50 Therefore, there are 15.0575 × 10^23 molecules in 2.50 moles of CH4.

Explanation:

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
