Q
What is concentration
A
the amount of a substance in a certain volume
2
Q
concentration gradient
A
the difference between two concentrations
3
Q
Linear relationships
A
a straight liner graph that goes through the origin point
4
Q
Directly proportional
A
When one variable increases so does the other
5
Q
Inversely proportional
A
When one variable goes up the other goes down
6
Q
What is the calculation for concentration
