How many moles of NH3 are in 3.0 L solution of 0.23M NH3? (Please show the steps)

0.69 moles of NH₃ are in 3.0 L solution of 0.23 M NH₃

Explanation:

Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain volume. In other words, molarity reflects the concentration of a solution, indicating the amount of moles of solute that appear dissolved in each liter of the mixture.

The Molarity of a solution is determined by:

Molarity is expressed in units .

In this case you know:

Replacing in the definition of molarity:

Solving:

number of moles of solute= 0.23 M* 3 L

number of moles of solute= 0.69

0.69 moles of NH₃ are in 3.0 L solution of 0.23 M NH₃
