4.4 Molar Concentration Flashcards
1
Q
Define Solution
A
A homogenous mixture with at least 2 substances (solute and solvent)
2
Q
Solute vs Solvent
A
Solute: lesser amount, dissolved in solvent
Solvent: Greater amount, usually determines phase of matter
3
Q
What is the Universal Solvent and why?
A
Water; size and polarity
4
Q
Define Molar Concentration
A
– AKA Molarity
– moles of solute per litre of solution
– most common concentration used in Chemistry
– Abbrev. M
5
Q
Molarity Formula
A
molar concentration = moles/volume
or
c = n/v
6
Q
What is the official SI unit for concentration?
A
kmol/m^3
