Chapter 2.4, Problem 2R
Summary Introduction

To analyze:

The number of molecules of a substance in the cell, which has volume of 0.000001 L (liter).

Given:

The concentration of substance is 0.00000001 M (molar) and the volume of cell is 0.000001 L.

Introduction:

There is a constant number of molecules present in one mole, which is represented as Avogadro’s number. The substances, which are involved in a biological reaction, are present in very small concentrations, which are mostly measured in millmoles or nanomoles. For example, even a small concentration of hormone is enough to create a signaling cascade in thousands of cells.
