Question

How many atoms of hydrogen are present in a container of water if you have 1.50 x 1023 atoms of oxygen present?​

Answer 1

Answer:

3.00 × 10²³ atoms H

Explanation:

Step 1: Given data

• Atoms of oxygen in water: 1.50 × 10²³ atoms

• Chemical formula of water: H₂O

Step 2: Calculate the number of atoms of hydrogen

According to the chemical formula of water, the atom ratio of H to O is 2:1.

1.50 × 10²³ atoms O × 2 atoms H/1 atom O = 3.00 × 10²³ atoms H
