Question

Hydrogen has two stable isotopes, with molar mass respectively 1 and 2. While oxide stable isotopes with molar mass respectively 16, 17, 18. Find how many different water molecules.

Answer 1

In a molecule of water (H2O), there are 2 hydrogen atoms and 1 oxygen atom. To find the total number of hydrogen atoms in a given number of water molecules, you multiply the given number by 2.

Step-by-step explanation:

In a molecule of water (H2O), there are 2 hydrogen atoms and 1 oxygen atom. To find the total number of hydrogen atoms in a given number of water molecules, you multiply the given number by 2 (since each water molecule has 2 hydrogen atoms). For example, if you have 3 water molecules, you would have 3 x 2 = 6 hydrogen atoms.
