I REALLY NEED HELP!! Is rubbing alcohol polar, non polar or ionic? Does it mix with water? Does it mix with vinegar?
Taya2010 [7]

Answer:

You can mix both with rubbing alcohol, and rubbing alcohol is ionic.

Explanation:

To mix them together:

Combine 1 cup rubbing alcohol, 1 cup water, and 1 tablespoon of white vinegar into a spray bottle. The solution can kill germs and clean counters, according to Reader's Digest.

Rubbing alcohol is both polar and iconic.

Hope that this helps you and have a great day :)

How many liters of 0.1107 M KCI contain 15.00 g of KCI (FW 74.6 g/mol)? O0.02227 L O 0.5502 L 01661 L O 1.816 L 18.16 L
Greeley [361]

Answer:

1,816 L

Explanation:

Molar concentration or molarity is a way to express the concentration of a chemical in terms of moles of substances per liter of solution.

To obtain the liters of this solution you must convert moles/L to g/L with formula weight (FW), thus:

0,1107 mol of KCl / L × (74,6 g / mol) = 8,258 g of KCl / L.

It means that in one liter you have 8,258 g of KCl. Thus, 15,00 g of KCl are contained in:

15,00 g × (1 L / 8,258 g) = 1,816 L

I hope it helps!
