Chapter 4, Problem 4.167QP

Interpretation Introduction

Interpretation: The time in seconds to transport enough $N{a}^{+}$ ions to increase its concentration by $8.0\times {10}^{-3}M$ in a cell whose intracellular volume is $2.0\times {10}^{-10}mL$ has to be determined.

Concept introduction:

• Amount of substance (mol) can be determined by using the equation,

$\text{Amount}\text{of}\text{substance}\text{(}\text{mole})\text{= Concentration}\times \text{Volume}$

$Numberofions/atoms=Amountofsubs\tan ce\left(mole\right)\times 6.022\times {10}^{23}$
