How much potassium chloride in grams is needed to prepare {eq}1500\ ml {/eq} solution of {eq}\rm 3\ M\ KCl {/eq} solution?
Question:
How much potassium chloride in grams is needed to prepare {eq}1500\ ml {/eq} solution of {eq}\rm 3\ M\ KCl {/eq} solution?
Molarity:
A quantitative method to express the concentration of a solution is by the use of molarity. The molarity of a solution is defined as the moles of solute per liter of solution.
{eq}Molarity~=~\frac{mol~solute}{liter~solution} {/eq}

View this answerWe begin by determining the moles of KCl present in 3 M of a 1.5 L solution. ( 1500 mL = 1.5 L)
{eq}mol~KCl~=~(1.5~L)\times(3.00\frac{mol}{L})~=~4.5~...
