1. Concentration %

2. C=m/V Review From Last Class Solution = solute + solvent Concentration
C: concentration (g/L)
m: mass of solute (grams)
V: volume of solution (litres)

3. Percentage 10 10

4. Percent
If we’re a class of 29 students and 4 students went to the science fair, what percentage of students went?

5. Percent m/V
We can also measure concentration in % (m/V)

6. Percent m/V
100ml of solution
1 ml of water (solvent)
1 g of solute

7. In other words X% = Xg/100ml
So if I have an 8% (m/V) solution, how many grams of solute do I have in 100ml of solution?
