Chapter 19, Problem 89E

Interpretation Introduction

Interpretation:

The molar mass of the protein is to be calculated.

Concept introduction:

The weight of one mole of a substance is known as its molar mass. Its unit is either in $\text{Kg/mol (Kilogram per mole)}$ or $\text{g/mol (gram per mole)}$.

The osmotic pressure can be calculated using the following formula:

$\text{Osmotic pressure }=\text{M}\times \text{R}\times \text{T}$ (1)

Where,

$\begin{array}{c}\text{M}=\text{Molarity of the solution}\\ \text{R}=\text{Gas constant}\\ \text{T}=\text{Temperature}\end{array}$

The molarity can be calculated using the following formula:

$\text{M }=\frac{\text{Number of moles }\left(\text{n}\right)}{\text{Volume of solution}\left(\text{V}\right)}$ (2)

The molar mass can be calculated using the following formula:

$\text{Molar Mass}=\frac{\text{Mass}\left(\text{m}\right)}{\text{Number of moles}\left(\text{n}\right)}$ (3)
