Question

How many grams of glucose, `C_6H_12O_6`, are needed to make 1500 mL of an intravenous D5W solution (5.0% (w/v) glucose solution)?

Answer 1

Recall,

`%w"/"v = "g"/(100"mL")`

`5.0%` w/v glucose has `5.0"g"` glucose per `100"mL"` of water.

Hence,

`1500"mL" * (5.0"g")/(100"mL") approx 75"g"`

of glucose are in the solution, given your data.
