Question

A 5.00% (m/v) dextrose (glucose) solution is typically used as an IV solution for patients with low blood sugar that need carbohydrates and/or have fluid loss.   This solution can be made by weighing 5.00 g glucose and dissolving it in enough water to make 100. mL of solution.  

A patient needs at least 2.00 L of specialized IV of 7.50% (m/v) dextrose solution.  A sterile solution was made by doing the following:  150. g glucose was dissolved in 2.330 kg of water to make a solution volume of 2.00 L .  The molar mass of dextrose (glucose) is 180. g/mole. 

(a)  What is the density of the solution?     g/mL

(b)  What is the %(m/m) of the solution?   % (m/m)

(c)  What is the molarity of the solution?   M

(d)  What is the molality of the solution?   m
