How to find the number of anions in a molar aqueous solution?

Answer 1

To find the number of anions in a molar aqueous solution, you need to calculate the number of moles of ions present in the solution.

Step-by-step explanation:

The number of anions in a molar aqueous solution can be determined by calculating the number of moles of ions present in the solution. To do this, you can follow these steps:

1. Convert the mass of the solute to moles using the molar mass of the compound.
2. Determine the number of moles of ions present in the solution using the stoichiometry of the compound.

For example, let's say we have a molar solution of NaCl. The molar mass of NaCl is 58.44 g/mol. If we dissolve 5 grams of NaCl in water to make a 1 L solution, we can calculate the number of moles of NaCl using the molar mass:

5 g NaCl / (58.44 g/mol) = 0.086 mol NaCl

Since NaCl dissociates into one Na+ ion and one Cl- ion, the number of moles of ions present in the solution is also 0.086 mol.
