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

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
