Solved: Specify the number of hydrogen atoms (white) represented in each set of

Problem 91P

Specify the number of hydrogen atoms (white) represented in each set of molecular models:

(a) 

(b) 

(c) 

Solution 91P:

Here, we are going to calculate the number of hydrogen  atoms present in each  set of molecular models.

Atom is the smallest tiny representation of an atom.

Chemical formula is the representation of the number of atoms present in the molecule or molecular compound .

(a)

It is a model of Water molecule (H2O)

Total number of Hydrogen atoms in (a) = 2 x 4 =8

(b)

It is a model of methane molecule (CH4)

Total number of Hydrogen atoms in (b) = 3 x 4 =12

(c)

Total number of Hydrogen atoms in (c) = 2 x 6 =12
