Question

Calculate the number of molecules in 6.50 mol of CH4, (Ans: 3.914x10" molecules)​

Answer 1

Answer:

We know that one mol any substance contains Avogadro number of molecules .

Number of molecules

= Number of Mol × 6.022 × 10^23

= 6.50 × 6.022 × 10^23

= 39.143 × 10^23

So 6.50 Mol of CH4 contains 39.143×10^23.

Explanation:

Avogadro number (6.02 x 10^23) is how many molecules there are in a mole.

so if you have 6.5 moles, you multiply 6.5 x 6.02 x 10^23.

which comes out to about 39.13 x 10^23, or if your a visual person 3,913,000,000,000,000,000,000,000 molecules in 6.5 moles of CH4

hope this helps,
