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

• M₁ V₁ = M₂ V₂

• V x M x MM = g

• none of these choices

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

____________ 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.
