Chapter 5, Problem 5.29E

(a)

Interpretation Introduction

Interpretation:

When the body contains $\text{1}\text{.75 g}·{\text{L}}^{\text{-1}}\text{ NaCl and 40}\text{.0 g}·{\text{L}}^{\text{-1}}{\text{ dextrose (C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}\text{)}$, the total molar concentration of all solutes in the solution has to be calculated.

Concept introduction:

The molar concentration can be calculated by using following formula,

  $Molarconcentration\text{ =}\frac{\text{Number}\text{of}\text{moles}}{1Literofsolution}$

(b)

Interpretation Introduction

Interpretation:

Osmotic pressure of solutions at ${25}^{\text{o}}\text{C}$ has to be calculated.

Concept introduction:

Osmotic pressure can be calculated by using following formula,

  $\begin{array}{l}\text{Π}\text{=}\frac{\text{nRT}}{\text{V}}\\ \\ \text{Where,}\\ \text{Π}\text{-}\text{Osmatic}\text{pressure}\\ \text{V}\text{-}\text{Volume}\\ \text{n}\text{=}\text{moles}\\ \text{T}\text{-}\text{Temperature}\\ \text{R}\text{-}\text{Gas}\text{constant}\end{array}$
