Question

Put these solutions in order in terms of increasing density (1-Lowest and 3 -Highest).

a. Isopropyl alcohol
b. 10%NaCl
c. Water

Answer 1

The order of increasing density is isopropyl alcohol, followed by water, and then 10% NaCl solution, since the presence of salt increases the density of the solution beyond that of pure water.

Step-by-step explanation:

To arrange the solutions isopropyl alcohol, 10% NaCl (sodium chloride), and water in order of increasing density, we must consider the typical density values of each component.

1. Isopropyl alcohol (density: approximately 0.785 g/ml)
2. Water (density: approximately 1.000 g/ml at 4 degrees Celsius)
3. 10% NaCl (density: greater than 1.000 g/ml because the salt increases the mass without significantly increasing volume)

Therefore, the correct order from lowest to highest density is isopropyl alcohol, water, then 10% NaCl solution.
