Answer to Question #91435 in Algebra for Tina

Question

A prefilled bag of infusion fluid contains a concentration of 0.5% of the medication and you are asked to administer 50mgs.How many mls do you administer to give the required dose?

Answer 1

Using formula:

 Mass by Volume percentage =(Mass of solute in grams/Volume of infusion fluid in ml) x 100%

0.5% =( Mass of solute in grams/Volume of infusion fluid in ml) x 100%

Mass of the medication per 1 ml is equal 0.5/100 grams = 0.005 grams = 5 mg.

To administer required dose we need 50/5 ml = 10 ml of infusion fluid.

Answer: 10 ml.
