A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?

Respuesta :

Answer:

The average diffusion distance is 2.1 mm

Explanation:

Given

Diffusion distance of the four potato squares are;

[tex]Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm[/tex]

Required

Average Diffusion Distance

To calculate the average diffusion distance; we simply calculate the mean of the student recordings

Mean is calculated as thus;

[tex]Mean = \frac{\sum x}{n}[/tex]

Where x is the individual distance of the potato squares

[tex]\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm[/tex]

[tex]\sum x = 8.4mm[/tex]

n is the number of potato squares

n = 4

[tex]Mean = \frac{\sum x}{n}[/tex]

[tex]Mean = \frac{8.4 mm}{4}[/tex]

[tex]Mean = 2.1 mm[/tex]

Hence, the average diffusion distance is 2.1mm
