if you diluted 145 ml of a 9% benzocaine lotion to 6% how much could you produce
since 6% is 2/3 of 9%, you can produce 3/2 the volume, or 217.5ml
You need to prepare 180g of a 10% cream using 30% stock cream base.how much is needed for each
To find out how much 6% benzocaine lotion you can produce, we need to use the concept of dilution. Dilution involves adding a solvent (in this case, an inactive ingredient) to reduce the concentration of the solute (benzocaine).
First, let's calculate the amount of benzocaine present in the original 9% benzocaine lotion (before dilution):
9% of 145 ml = (9/100) * 145 ml
= 13.05 ml
Now, let's determine the volume of the new 6% benzocaine lotion we can produce. Let's assume the final volume is "x" ml.
Concentration * Volume = Concentration * Volume
9% of 145 ml = 6% of x ml
13.05 ml = (6/100) * x ml
Now, we can solve for x:
x = (13.05 ml) / (6/100)
x ≈ 217.5 ml
Therefore, you can produce approximately 217.5 ml of a 6% benzocaine lotion by diluting 145 ml of a 9% benzocaine lotion.
To find out how much 6% benzocaine lotion you can produce, you need to determine the volume of the final solution after dilution.
First, let's calculate the total amount of benzocaine in the 9% lotion before dilution:
Volume of 9% benzocaine lotion = 145 ml
Concentration of benzocaine in the 9% lotion = 9%
Benzocaine in 9% lotion = Volume × Concentration
= 145 ml × (9/100)
= 13.05 ml
So, the 9% benzocaine lotion contains 13.05 ml of benzocaine.
Next, let's calculate the volume of the final 6% benzocaine lotion after dilution:
Concentration of benzocaine in the final 6% lotion = 6%
Let the volume of the final 6% lotion be V.
Benzocaine in 9% lotion = Benzocaine in 6% lotion
13.05 ml = V ml × (6/100)
Solving for V:
V = (13.05 ml × 100) / 6
= 217.5 ml
Therefore, you can produce 217.5 ml of 6% benzocaine lotion by diluting 145 ml of 9% benzocaine lotion.
