how many oxygen atoms are there in 4 molecules of h2o?
how many oxygen atoms are there in 4 molecules of h2o?
Answer
Explanation:
Step1: Identify oxygen - atom count per water molecule
Each $H_2O$ molecule has 1 oxygen atom.
Step2: Calculate oxygen - atom count for 4 water molecules
If 1 $H_2O$ molecule has 1 oxygen atom, then for 4 $H_2O$ molecules, the number of oxygen atoms is $4\times1 = 4$.
Answer:
4
