Q: Using the ninth image, what is the molarity of a solution prepared by dissolving 58 grams of NaCl (molar mass = 58 g/mol) in enough water to make 1 L of solution?

$$M = \frac{58\,g}{58\,g/mol \times 1\,L} = 1\,M$$

Q: Referencing the tenth image, what is the molality of a solution prepared by dissolving 58 grams of NaCl (molar mass = 58 g/mol) in 1 kg of water?

$$m = \frac{58\,g}{58\,g/mol \times 1\,kg} = 1\,m$$

Question 1

Which of the following best describes the process shown in the first image, where a tea bag is placed in water and the solution becomes darker over time?

Accepted Answer

Dissolution of solute into solvent

Question 2

Referencing the second image, which property of water is illustrated by the partial charges on the oxygen and hydrogen atoms?

Accepted Answer
