How can I prepare a solution of 12 g 50% (w/v) NaOH?
Question:
How can I prepare a solution of 12 g 50% (w/v) NaOH?
Weight Per Volume Percent
The weight per volume percent has the units (w/v)%. It is defined as the ratio of the mass of the solute divided by the volume of solution times 100. The formula for weight per volume percent is given below:
{eq}(w/v ~\%\ )~=~\frac{mass~solute~(g)}{volume~solution~(mL)}\times100 {/eq}
