the saturant

What is it about the water molecule that makes it a great solvent?

water demonstrates polarity; a partial charge on each side of the molecule

due to its molecular formula

it has a liner molecular shape

due to it's non-polar molecular structure

What is the correct formula to solve for the Molarity of a solution that has .4 moles of HCl in 9.5 L of solution?

M = 9.5 L / .4 mol

M₁V₁=M₂V₂

M = .4 mol / 9.5 L

none of the other choices

A sample of 0.0255 mol potassium hydroxide, KOH, was dissolved in water to yield 10.0 mL of
solution. Which amount would you need to change to solve for molarity?

change .0255 moles to grams

change 10 mL to L

change both values to grams and L

leave it as it is

A questions asks, "what volume of 0.125 M KMnO4 is required to yield 0.180 mol of potassium permanganate,

KMnO4?" What is the correct formula set up to solve for this problem?

M x V = #moles

M₁V₁ = M₂V₂

V x M x MM = g

none of these choices

11.

In this scenario, which formula should you use to solve it? How many mL of a 1.00 M stock solution should be

used to mak 2.00 L of a 0.300 M sulfuric acid solution

molarity formula, (Moles solute/ L of solution)

dilution formula, M₁V₁= M₂V₂

M x V = #moles

V x M x MM = g

12.

____________ is the process whereby particles of a solvent completely surround the particles of a solute, disperse them throughout the solvent particles, and hold them in solution.

solvation

immisciblation

dissolution

saturation
