graph with moles of kool-aid powder on x-axis and molarity on y-axis, data points plotted

which statement best describes the relationship shown in the graph between moles of kool-aid powder and solution molarity?

• ⃝ as the moles of kool-aid powder increases, molarity decreases.
• ⃝ there is no consistent relationship between moles and molarity.
• ⃝ molarity increases as moles of kool-aid powder increase.
• ⃝ molarity is constant regardless of kool-aid amount.

Explanation:

To determine the relationship, we analyze the graph: the x - axis is moles of Kool - Aid powder and the y - axis is molarity. As the values on the x - axis (moles) increase, the values on the y - axis (molarity) also increase. So we can eliminate the option that says molarity decreases, the option that says there's no consistent relationship, and the option that says molarity is constant. The correct relationship is that molarity increases as moles of Kool - Aid powder increase.

Answer:

Molarity increases as moles of Kool - Aid powder increase (the corresponding option among the given choices, e.g., if the option was labeled as C: Molarity increases as moles of Kool - Aid powder increase, then the answer would be C. Molarity increases as moles of Kool - Aid powder increase)
