Calculate the number of grams of dextrose in 250mL of D5W.

Question

I know that the answer is 12.5g, but I do not understand the work. Please help.

Answer 1

never mind... I got it! :-)

FYI--
(250 mL/1) * (5/100) = 12.5g

This is because D5W means dextrose in 5% water.

Answer 2

250/1000x5= 1.25
