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.

Answer: 1.51x10²⁴ molecules CH4

Explanation: Solution attached:

2.50 moles CH4 x 6.022x10²³ molecules CH4 / 1 mole CH4

= 1.51x10²⁴ molecules CH4
