dilution and molarity Flashcards
(11 cards)
1
Q
A measure of concentration, defined as moles of solute per liter of solution.
A
Molarity (M)
2
Q
Dilution Equation:
A
M1 V1 = M2 V2
3
Q
Add water = concentration ___________
A
DECREASES
4
Q
Evaporate solvent = concentration ______________________
A
INCREASES
5
Q
equation: moles from mass
A
moles = mass (g)/ molar mass (g/mol)
6
Q
mass percent equation
A
% mass = mass of solute/ mass of solution x 100
7
Q
equilibrium constant equation
where:
aA + bB ⇌ cC + dD
A
Kc = [C]^c [D]^d / [A]^a [B]^b
8
Q
reaction quotient
A
Q = products/ reactants
9
Q
Q<K
A
Forward reaction proceeds
10
Q
Q>K
A
Reverse reaction proceeds
11
Q
Q=K
A
System is at equilibrium
