the answer is D because if an equal amount of heat is absorbed by the water in the containers, both water temperatures will increase, but Container B's will increase more.
When heat is absorbed by a substance, the substance's temperature increases. The amount that the temperature increases depends on the volume of the substance—the greater the volume, the less the temperature increases.
The water in Containers A and B has the same temperature, but Container A's water has a greater volume. If an equal amount of heat is added to both containers, Container A's water temperature will not increase as much as Container B's.
Answer:Osmotic pressure is the minimum amount of pressure a solution must exert in order to prevent from crossing a barrier by osmosis. Solute molecules have difficulty crossing semipermeable membranes, so the more solutes that are in a solution, the higher the osmotic pressure will be. Between 30% sucrose and 60% sucrose, 60% sucrose will have a greater osmotic pressure than 30% because it has a higher percentage of solutes. However, since sucrose has a higher potential to cross semipermeable membranes and is more absorbable than magnesium sulfate, magnesium sulfate would have a higher osmotic pressure than 60% sucrose even though 60% sucrose has higher molecules.

Answer:
Percent Composition of Compounds
The percent composition (by mass) of a compound can be calculated by dividing the mass of each element by the total mass of the compound.
LEARNING OBJECTIVES
Translate between a molecular formula of a compound and its percent composition by mass
- The atomic composition of chemical compounds can be described in a variety of ways, including molecular formulas and percent composition.
- The percent composition of a compound is calculated with the molecular formula: divide the mass of each element found in one mole of the compound by the total molar mass of the compound.
- The percent composition of a compound can be measured experimentally, and these values can be used to determine the empirical formula of a compound.
- percent by mass: The fraction, by weight, of one element of a compound.
- The atomic composition of chemical compounds can be described using a variety of notations including molecular, empirical, and structural formulas. Another convenient way to describe atomic composition is to examine the percent composition of a compound by mass.
- Percent Composition by Mass
Percent composition is calculated from a molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of the entire compound. This value is presented as a percentage.
