multiple choice question
when comparing two full 1 liter bottles of solutions, which one contains more water: 5% glucose solution or 10% glucose solution?

○ 5% glucose solution
○ 10% glucose solution
○ they both have the same amount of water because they are both 1 liter.

Explanation:

A glucose solution's water content is the total volume minus the glucose volume. For a 1 - liter solution, the percentage of glucose determines the glucose volume. A 5% glucose solution has 5% of 1 liter as glucose, so water is \(1 - 0.05\times1= 0.95\) liters. A 10% glucose solution has 10% of 1 liter as glucose, so water is \(1 - 0.1\times1 = 0.9\) liters. Since \(0.95>0.9\), the 5% glucose solution has more water.

Answer:

A. 5% glucose solution
