Question

A cell membrane has a thickness of about 7 nm. How many cell membranes would it take to make a stack 2.3 in high?

Answer 1

There are 8345714 cell membranes.

Step-by-step explanation:

It is given that,

The thickness of a cell membrane is 7 nm

We need to find the number of cell membranes would it take to make a stack 2.3 inches high.

Firstly, the units must be same i.e. converting 2.3 inches to m

1 inch = 0.0254 m

2.3 inches = 0.05842 m

Let there are n number of cell membranes. So,

`n=\frac{\text{stack height}}{\text{1 membrane thickness}}\\\\n=(0.05842)/(7* 10^(-9))\\\\n=8345714.28`

or

n = 8345714 cell membranes
