3. A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL. Calculate the percentage (v/v) of liquid me

Marina CMI [18]

Answer:

The percentage (V/V) of liquid menthol in the ointment is 1.59%.

Step-by-step explanation:

Given : A prescription for an ointment has 3.5 mL of liquid menthol in a total of 220 mL.

To find : Calculate the percentage (V/V) of liquid menthol in the ointment ?

Solution :

Volume of liquid menthol is $V_m= 3.5\ mL$

Total volume of ointment is $V_t= 220\ mL$

The V/V percentage is given by,

$\frac{V}{V}\%=\frac{V_m}{V_t}\times 100$

$\frac{V}{V}\%=\frac{3.5}{220}\times 100$

$\frac{V}{V}\%=0.0159\times 100$

$\frac{V}{V}\%=1.59\%$

Therefore, the percentage (V/V) of liquid menthol in the ointment is 1.59%.
