Correct option is B
To calculate the mass by mass percentage of the solution, we can use the following formula:
Mass by mass percentage = (Mass of solute / Total mass of solution) * 100
In this case:
- Mass of solute (sugar) = 50g
- Mass of solvent (water) = 450g
- Total mass of solution = 50g + 450g = 500g
Plugging these values into the formula:
Mass by mass percentage = (50g / 500g) * 100 = 10%
Therefore, the concentration of the solution in terms of mass by mass percentage is 10%.
So, the correct answer is 2. 10%.
