There are ___ atoms of oxygen in 300 molecules of CH3CO2H a) 300 b) 600 c) 150 d) 3.6 x 10^36

The correct option is b) 600

Explanation:

Molecules are formed when two atoms of same or different elements combine together.

Atoms are the smallest unit of matter that combines to form a compound.

For the given chemical compound,

Given number of molecules = 300 molecules

In 1 mole of the given chemical compound, there are 2 atoms of carbon, 4 atoms of hydrogen and 2 atoms of oxygen

Number of atoms of oxygen =

Number of atoms of oxygen =

Hence, the correct option is b) 600
