We’re being asked to determine the mass of glucose that must be added in 63 g of water to make a 2.47 m solution.
Recall that molality is the ratio of the moles of solute and the mass of solvent (in kilograms).
In other words:
Determine the mass in grams of glucose (180.1 g/mol) that must be added to 63 g of water to make a 2.47 m solution. Give your answer to 2 decimal places.
A. 2.8x104 g
B. 4.59 g
C. 2.80 g
D. 444 g
E. 28.02 g/mol
