Convert a 0.9% glucose solution to g/ 100 ml.

How many grams of glucose would you need to add to 1 liter of water to make a 0.9% glucose solution? Use dimensional analysis.

If you had a 0.9% glucose solution how many mol/L do you have? Calculate glucose’s molecular weight first and then use dimensional analysis to calculate your final answer.

If you had a 0.9% glucose solution how many osmoles/L do you have? You have to take into account how many particles glucose dissociates into.

If you had a 0.9% NaCl solution how many osmoles/L do you have? You have to take into account how many particles NaCl dissociates into.

Answer:

If we consider a solution density of 1 g/ml, it is 0.9 g/100ml

Step-by-step explanation:

A solution 0.9% glucose can be expressed as follows:


(0.9 g glucose)/(100 g solution) \\

If the density of the solution (at a given temperature) is 1 g/ml, the solution concentration can be calculated as follows:


(0.9 g glucose)/(100 g solution) . (1 ml solution)/(1 g glucose) = (0.9 g glucose)/(100 ml solution)

So, to calculate a solution concentration in g/ml from a %w/w concentration you have to only divide it into the solution density. Remember that solution density depends on the temperature.
