Question:
What is the molarity of a 14.7% {eq}NaClO_3 {/eq} solution if the density of the solution is 1.09 g/mL?
(a) 0.138 M
(b) 1.51 M
(c) 0.092 M
(d) 0.00151 M
(e) 0.147 M
Molarity:
The molarity is the most common way in chemistry to define the concentration of a solute species inside of a solution (homogeneous mixture). The units are {eq}\rm mol/L {/eq} (abbreviated "M") because the molarity value describes the solute moles dissolved per liter of solution. If you need to calculate a molarity for a solute, then you may not know the solute moles and solution volume directly. However, you may know the solute concentration in a different form, such as a mass percent. You can find the molarity from other forms of solute concentration, provided you know the appropriate conversion factors.
