Amount in IV Fluid Questions

Given a volume of IV fluid and a dosage expressed in percent, what is the mass of a particular dosage?

Formula:
Concentration %
100
x Volume (mL)  =  Y (Dosage Amount in g)

Example: Calculate the amount of dextrose in 1000 mL D5W.
Concentration %
100
x Volume (mL)  =  Y (Dosage Amount in g)
5%
100
x 1000 mL  =  50 g

Example: Calculate the amount of sodium chloride in 2000 mL NS.
Recall NS is 0.9% NaCl (sodium chloride)
Concentration %
100
x Volume (mL)  =  Y (Dosage Amount in g)
0.9%
100
x 2000 mL  =  18 g
