What is the formula for Molarity
Molarity = moles/Liters
100
What is molarity?
Concentration of a solution in moles per liter
100
Increasing temperature (increases/decreases? rate of dissolving
increases

What is a polar molecule
a molecule with a negative and positive end. A NONsymmetrical molecule

Define Saturated Solution
When the maximum amount of solute is dissolved in a given amount of solvent. No more solute can dissolve
200
More collisions occur between solvent and solute when the solute's surface area is (greater/smaller)
greater

300
Define solute
the substance being dissolved
300
How does stirring solution affect the number of collisions between solute and solvent
the number of collisions increase
300
Water can only dissolve (nonpolar/polar) solutes

When a solution is diluted, what happens to the number of moles? What happens to the molarity?
moles stay the same molarity decreases
