Final Answer:
x1 = 25%, x2 = 50%, x3 = 25%
Step-by-step explanation:
To determine the concentrations in percent, we first need to know the total sum of the concentrations. Let's assume the total concentration is 100%. If x1, x2, and x3 represent three different concentrations, and the sum of these concentrations is 100%, we can fill in the blanks as follows:
x1 = 25%: This suggests that the first concentration constitutes 25% of the total.
x2 = 50%: The second concentration is 50%, making up half of the total.
x3 = 25%: The third concentration, like the first, is 25%, completing the total of 100%.
These values represent the relative proportions or percentages of the different concentrations within the total mixture.
Calculating concentrations and percentages in chemical solutions. Understanding how to express concentrations is essential in various scientific fields, particularly in chemistry and biology, where precise measurements play a critical role.
