Chapter 3.5 Fundamentals of Solution Stoichiometry

Question 1

What is the Concentration of a Solution?

Answer 1

the quantity of solute dissolved in a given quantity of solution
(solute quantity/solution quantity)

Question 2

Molarity (M) definition

Answer 2

expresses the concentration in units of MOLES of solute per LITER of solution

Question 3

Molarity (M) equation

Answer 3

M = (mol solute) / (L solution)

Question 4

Equation for solving dilution problems

Answer 4

M(dil) x V(dil) = M(conc) x V(conc)

M1 x V1 = M2 x V2

Question 5

Steps for solving stoichiometry of reactions in solution (4)

Answer 5

1. Balance the equation
2. Find the amount (mol) of one substance from the volume and molarity
3. Relate it to the stoichiometrically equivalent amount of another substance
4. Convert to the desired units
