Molar Concentrations Flashcards
Final prep
1
Q
Formula to determine molar concentration?
A
c = n/V
2
Q
What is c in c = n/V?
A
The molarity, or molar concentration (mol/L)
3
Q
What is n in c = n/V?
A
The amount of moles (mol)
4
Q
What is V in c = n/V?
A
The volume of the solution (L)
5
Q
What is the unit M?
A
M is the unit of molarity
It is short for moles per liter (mol/L)
6
Q
How could you determine the molarity of a solution using the weight and final volume?
A
Determine the amount of moles using n = m/M, then use the molar concentration formula c = n/V
7
Q
What formula can be used to estimate the amount of solute (m) required to prepare a solution? (Given volume, known concentration)
A
m = cMV
Where:
c = concentration (mol/L)
M = molar mass (g/mol)
V = volume (L)
