Chapter 12, Problem 12.86FU

Interpretation Introduction

Interpretation:

The mass of mannitol should be calculated.

Concept Introduction:

Mass/volume percent (m/V) concentration is defined as the mass of solute in grams for 100 mL of the solution. Here, mass of solute should be in grams and unit of volume of solution should be in millilitres.

Mathematically,

  $\begin{array}{l}\text{mass /volume percent}\left(m/V\right)=\frac{\text{mass of solute}\left(g\right)}{\text{volume of solute}\left(\text{mL}\right)+\text{volume of solvent}\left(\text{mL}\right)}\times 100\%\\ =\frac{\text{mass of solute}\left(g\right)}{\text{volume of solution}\left(\text{mL}\right)}\times 100\%\end{array}$
