How many moles of {eq}K^+ {/eq} are present in 343 mL of a 1.27 M solution of {eq}K_3PO_4 {/eq}?

Question:

How many moles of {eq}K^+ {/eq} are present in 343 mL of a 1.27 M solution of {eq}K_3PO_4 {/eq}?

Molarity:

The concentration of a solute and its dissolved ions can be expressed in terms of moles. Often, we find that the concentration of the solute is expressed in molarity. Molarity is denoted by the symbol M and is the ratio between the moles of solute and the total volume of the solution in liters. The molarity is also known as the molar concentration.
