If you diluted 95ml of a 7% benzocaine lotion to 5% how much could you produce? ___
To determine the final volume of the diluted benzocaine lotion, we can use the principle of dilution.
Let's first calculate the amount of pure benzocaine in the original 7% lotion.
7% of 95ml = (7/100) x 95ml = 6.65ml
Now, let's set up the equation for dilution:
(6.65ml of pure benzocaine) / (final volume) = 5%
We need to solve for the final volume.
(6.65ml) / (final volume) = 5/100
Cross multiply to solve for the final volume:
(6.65ml) = (5/100) x (final volume)
Divide both sides by (5/100):
final volume = (6.65ml) / (5/100)
Simplify:
final volume = 6.65ml x (100/5)
final volume = 133ml
Therefore, if you diluted 95ml of a 7% benzocaine lotion to 5%, you could produce approximately 133ml of the diluted lotion.
