Answer:
0.75mL
Explanation:
we have the density that is 0.1mg/mL and the mass (75mcg)
The unit in which the mass is expressed is microgram, we must pass it to milligrams to have all the data in the same units
To know how many mg are 75mcg we apply a rule of three
[tex]1mcg\longrightarrow 0.001 mg\\75mcg\longrightarrow x\\x=\frac{(75)(0.001)}{1}\\ x=0.075mg[/tex]
The density formula is given by the following equation
[tex]d=\frac{m}{V}[/tex]
now we clear the volume and replace the data
[tex]V=\frac{m}{d}\\ V=\frac{0.075mg}{0.1mg/mL} \\V=0.75 mL[/tex]
The necessary volume is 0.75 mL of pediatric digoxin injection
