Question

How many hydrogen atoms are there in the following compound: 4CH4. A)4 B)8 C)12 D)16

Answer 1

Answer:16

Explanation:

The coefficcient infront of the C for carbon applies to the whole molecule. H ALSO HAS A SUBSCRIBT OF 4. 4×4 is 16

Answer 2

Answer : The number of atoms of hydrogen present in $4CH_4$ are, (D) 16 hydrogen.

Explanation :

As we know that, $CH_4$ is a methane molecule that is made up of the combination of one carbon and four hydrogen atom.

In $4CH_4$ molecule, there are two elements which are carbon (C) and hydrogen (H).

The number of atoms of carbon = 4

The number of atoms of hydrogen = 4 × 4 = 16

Hence, the number of atoms of hydrogen present in $4CH_4$ are, (D) 16 hydrogen.
