Answer:
5 cc
Explanation:
.01 M * 500/1000 = .005 M needed
1.0 M * x .005 M
x =.005 liter 5 cc
5cc of 1M dilute to 500 cc
Answer:
0.10 L
Explanation:
First we <u>convert the 2.0 grams of solute</u> (meaning <em>sodium hydroxide</em>)<u> into moles</u>, using its <em>molar mass</em>:
- 2.0 g ÷ 40 g/mol = 0.05 mol NaOH
Then we can <u>calculate the required volume of solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- liters = moles / molarity
- 0.05 mol / 0.50 M = 0.10 L
Answer:
The doctor is discussing an Ocular Hypertension disease.
Explanation:
If we have a small space with a defined volume like in this case an eye, when we fill this space with a liquid, the liquid will occupy the whole volume available, and when it is much liquid or fluid, and the volume of the eye can not expand it will start to generate an internal pressure. This higher pressure is called Hypertension.
