What volume (L) of 2.00 M KCl solution contains 25.0 g of KCl? A) 0.672 B) 1.49 C) 0.335 D) 0.168

Question:

What volume (L) of 2.00 M KCl solution contains 25.0 g of KCl?

A) 0.672
B) 1.49
C) 0.335
D) 0.168

Molarity:

Molarity is a quantity used to express the molar concentration of chemical species in its solution. Molarity is the number of moles of a chemical species per unit liter of its solution.

{eq}\begin{align*} \text{Molarity}&=\frac{\text{Moles of Solute (mol)}}{\text{Volume of Solution (L)}}\\ \end{align*}{/eq}

We are given:

  • Mass of KCl, w = 25.0 g
  • Molarity of KCl solution, M = 2.00 M
  • Molar mass of KCl = 74.5 g/mol

We can put the values given in the...
