Final Answer:
Using the best-fit line on the graph, the predicted absorbance for a 200 mM drink mix solution is Type your answer here, and for a 300 mM drink mix solution, the predicted absorbance is Type your answer here.
Step-by-step explanation:
The best-fit line on a graph represents a trendline that helps predict values for measurements not taken in an experiment. To predict the absorbance for the 200 mM and 300 mM drink mix solutions, we use the best-fit line's equation. Typically, a linear regression equation y = mx + c represents this line, where y is the predicted value, m is the slope, x is the input variable, and c is the y-intercept.
With the standard curve obtained from experimental data, the absorbance is likely plotted against concentration. Utilizing the best-fit line equation derived from this data, substituting the concentrations of 200 mM and 300 mM into the equation for \(x\) allows us to predict their corresponding absorbance values.
Calculating these values using the established linear regression equation provides us with the predicted absorbance values for the 200 mM and 300 mM drink mix solutions based on the trendline established from the experimental data.
