An injection of 4 mg of Valium has been prescribed for a patient suffering from muscle spasms. A bottle of Valium labeled 5 mg/mL is on hand. How many mL should be injected?

Respuesta :

Given the patient is suffering from muscle spasms.

The mass of Valium to be injected to the patient suffering from muscle spasms =4 mg

Given the bottle of valium with a density of 5 mg/mL

We know that, Density = [tex]\frac{Mass}{Volume}[/tex]

Volume = [tex]\frac{Mass}{Density}[/tex]

Mass = 4 mg Valium

Density = 5[tex]\frac{mg}{mL}[/tex]

Calculating the volume from mass and density:

Volume of valium to be injected[tex]= 4 mg *\frac{1mL}{5mg}[/tex]=0.8mL

Therefore, a volume of 0.8 mL of valium is to be injected to the patient.
