Final answer:
To calculate the mass/mass percent concentration of a solution, divide the mass of dextrose by the total mass of the solution and multiply by 100%. However, without knowing the total mass of the solution, it is impossible to calculate the mass/mass percent concentration.
Step-by-step explanation:
The question is asking about the mass/mass percent concentration of a dextrose solution. To calculate this, you need to divide the mass of dextrose by the total mass of the solution and multiply by 100%. In this case, the mass of dextrose is 100g and the total mass of the solution is unknown.
Therefore, you cannot determine the mass/mass percent concentration of the solution with the given information. You need to know the total mass of the solution to calculate it.
