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?

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 =

Volume =

Mass = 4 mg Valium

Density = 5

Calculating the volume from mass and density:

Volume of valium to be injected=0.8mL

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

answer: they produce more slow than unicellular organisms.
