Final answer:
To determine the amount of solvent in a solution with a solute/solution ratio of 2:5, set up a proportion and solve for the amount of solvent. The amount of solvent is 2/5 units.
Step-by-step explanation:
To determine the amount of solvent in a solution with a solute/solution ratio of 2:5, we can set up a proportion. Let's say the solute is represented by 2 units and the solution is represented by 5 units. If we let x be the amount of solvent, we can set up the following proportion: 2/5 = x/1. Solving this proportion, we find that x = 2/5, which means that there are 2/5 units of solvent in the solution.
