Its a dependent variable.
in independent variable is something being changed in an experiment to test the effects on the dependent variable. the dependent variable is what is being tested.
First, you need to convert all units to calculate what dose the doctor ordered.
1 dram = 4 mL
So, it must be given 4 mL of medication
1 cc = 1 mL
So, if t<span>he vial states that there is 1 mg in 1 cc </span>, that means the concentration is 1 mg in 1 mL or, 1 mg/mL.
Now, we need to calculate what is the dose of medication in 4 mL:
1 mg is in 1 mL, how many mg is in 4 mL:
1 mg : 1 mL = x : 4 mL
Crossing the products:
x · 1 = 1 mg · 4
⇒ x = 4 mg
Answer:
c
