  1. Using the formula, calculate the volume of 12.0 M HCl needed to make 0.250 L of 0.500 M HCl.

0.0104 L

300
the substance present in the largest quantity in any solution.
What is a solvent
300
The molarity of 1.2 grams of hydrochloric acid in a 25mL solution.
What is 1.35 M
300
These solutes DO NOT dissolve in non-polar solvent.
What is ionic or polar.
300

I have 345 mL of a 1.5 M NaCl solution. If I boil the water until the volume of the solution is 250 mL, what will the molarity of the solution be?

M1V1 = M2V2 

(1.5 M)(345 mL) = x (250 mL) 

x = 2.07 M 

400
Describes a solution that contains the maximum amount of the solute that dissolves in a given solvent.
What is saturated
400
You would need this many grams of sodium carbonate to make 45mL of a 0.12M solution.
What is .57 grams
400
These 2 intermolecular forces must be broken for a solute to dissolve in a solvent.
What is the intermolecular forces between solute-solute molecules & solvent-solvent molecules.
400

If I add water to 100 mL of a 0.15 M NaOH solution until the final volume is 150 mL, what will the molarity of the diluted solution be?

M1V1 = M2V2 

(0.15 M)(100 mL) = x (150 mL) 

x = 0.100 M 

500
The process in which a compound separates into fragments, such as simpler molecules atoms, radicals, or ions.
What is dissociation.
500
You would dissolve 120 grams NaOH in 1.5L to make a solution with this molarity.
What is 2 M
500
Solubility decreases with an increase in temperature when this type of solute is added.
What is a gas.
500

How much water would I need to add to 500 mL of a 2.4 M KCl solution to make a 1.0 M solution?

1200 mL will be the final volume of the solution. However, since there’s already 500 mL of solution present, you only need to add 700 mL of water to get 1200 mL as your final volume. The answer: 700 mL.
