Answer:
4.82 g
Explanation:
To solve this problem we'll use the <em>definition of molarity</em>:
- Molarity = moles / liters
We are given the volume and concentration (keep in mind that 100mL=0.100L):
- 0.825 M = moles / 0.100 L
Now we <u>calculate the number of NaCl moles required</u>:
Then we convert 0.0825 NaCl moles into grams, using its molar mass:
- 0.0825 mol * 58.44 g/mol = 4.82 g
Answer: "Yes".

Answer:
Adhesive forces and cohesive forces
Explanation:
Cohesive forces is how much the water molecules stick to each other and adhesive forces are to which extinct they stick to other surfaces.
When we pull the paperclip upward the water molecules adhere to it due to adhesive forces. While the water on the clip is remain connected to water in the glass because of cohesive forces.
So if the adhesive forces dominates the water will be pulled out and if the cohesive forces dominate it will remain with other water in the cup.
Answer:
how far down stream will the concentration be reduced by from 10 mg/L to 1 mg/L? = 108meters
