Calculate the volume of pure water that used to dilute 100 ml of 12 M NaOH to 4.75 M.

152.63 ml.

Explanation:

By proportion to get a 4.75 M solution the volume will be

(12/4.75) * 100 = 252.63 ml

So the answer is 152.63 ml.

molarity=number of moles/volume

First we find the number of moles of NaOH we have the molarity and the volume we transform mililiters in liters 100ml=0.1l

12=n/0.1 n=1.2 moles of NaOH

now we find the volume of the second solution

4.75=1.2/V

V=1.2/4.75=0.252l

0.252-0.1=0.152liters=152ml of pure water used to dilute

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
