If you dissolve 27 g of sugar into 155 mL of water, what can you conclude about the mass and volume of the resulting solution? Assume a density of 1.00 g>mL for the water. a. mass = 155 g; volume = 155 mL b. mass = 182 g; volume = 155 mL c. mass = 182 g; volume 7 155 mL d. mass = 155 g; volume 7 155 mL

Understanding the mass of a solution is integral to many scientific calculations, such as preparing solutions for lab experiments. The mass of a solution is simply the total mass of all the components that make up the solution. In the case of dissolving sugar in water, you add the mass of sugar to the mass of water to find the total mass of the solution.

Given that the density of water is 1.00 g/mL, we leverage this fact to establish that the volume in milliliters is numerically equal to the mass in grams for water. If you dissolve 27 g of sugar into 155 mL of water, the total mass of the solution is calculated by adding the mass of the dissolved sugar to the mass of the water, which yields a total of 182 g.

The volume of a solution refers to the space it occupies, typically measured in liters or milliliters. When discussing the volume of a solution made by dissolving a substance in water, a common assumption is that the final volume doesn't significantly change from the original volume of water.

In the context of dissolving a small amount of sugar in a larger amount of water, like 27 g of sugar in 155 mL of water, it's assumed that the sugar particles occupy the spaces between water molecules, and thus the volume stays approximately the same, that is, 155 mL. This is a simplification, as some substances can cause the volume to increase or decrease upon dissolving.

Density is a measure of how much mass is contained in a given volume, often expressed as grams per milliliter (g/mL) or kilograms per liter (kg/L). Concentration, on the other hand, describes how much of a substance is dissolved within a solution and can be given in terms like molarity, molality, or mass percent.

The density of water is given as 1.00 g/mL, meaning that each milliliter of water has a mass of 1 gram. When substances are dissolved in water, this density can change depending on the mass and volume of the dissolved substance. For our sugar in water example, while the concentration of sugar increases, the overall density of the solution does not necessarily increase in a straightforward manner since the volume of the solution remains virtually unchanged.

The process of dissolving involves mixing a solute (like sugar) into a solvent (like water) to create a solution. Depending on the solute and solvent, the substances can mix at the molecular level through a variety of interactions. In our exercise, sugar molecules interact with water molecules through hydrogen bonding, which allows them to spread evenly in the solution.

A key point to remember is that upon dissolving, the solute particles are dispersed uniformly in the solvent, forming a homogenous mixture. The amount of solute that can be dissolved in a solvent varies, leading to various types of solutions such as saturated, unsaturated, and supersaturated. The solubility, the maximum amount of solute that can dissolve at a given temperature, is an important factor for these types of solutions.
