You have a mixed solution in a beaker which contains a bag of 4g dissolved in 15ML of water. The beaker contains 50g of glucose dissolved in 200mL of water. What is the percentage concentration of the two solutions? Does the glucose diffuse out or into the bag? And what will happen to the water?
The percentage concentration can be calculated using the following formula:
percentage concentration = (mass of solute / mass of solution)*100
The mass of solution is the combined mass of the solute and the solvent (water). You have been given the amount of water as a volume. The corresponding mass can be easily calculated using the density of water (1 g/mL).
So for the bag, you ...
The solution answers the question step-by-step using formulas and explanation.
