Chemistry- moles, volume

Question

A patient needs to receive 85 grams of glucose every 12 hours. What volume of a 5.0%(m/v) glucose solution needs to be administered to the patient each 12 hours?

Answer 1

5% (m/v) is 5 g/100 ml or 0.05 g/ml

So to get 85 g you need ...

0.05 g/ml (x ml) = 85 g and x = 1700 mls

So the patient would need 1700 mls every 12 hours
