Question

Calculate the number of molecules in 4 g of methane.​

Answer 1

Answer:

1.505 × 10²³ molecules of methane are present in 4g methane.

Explanation:

Gram Molecular mass of CH4 = 16g

16g of CH4 = 6.023 × 10²³ molecules

4g of CH4 = ? molecules

4/16 × 6.023 × 10²³ molecules

6.023/4 × 10²³

1.505 x 10²³ molecules
