Asolution of ammonia and water contains 1.80×1025 water molecules and 7.00×1024 ammonia molecules. how many total hydrogen atoms are in this solution?

6.40x10²⁵ hydrogen atoms

Explanation:

The solution contains:

We need to calculate the total of hydrogen atoms (H) in the solution.

Lets now calculate the number of hydrogen atoms in the solution:

total H atoms = (H atoms in water molecules) + (H atoms in ammonia molecules)

total H atoms = (2 x 1.80x10²⁵) + (4 x 7.00x10²⁴) =

total H atoms = 3.60x10²⁵ + 2.80x10²⁵ = 6.40x10²⁵

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
