You dilute 50.0L0.397MH2O2 to a final volume of 9.60mL. What is the molarity of the final solution? Enter the numerical value in scientific notation, to 3 significant figures, without units. To enter scientific notation, use E-format, where 1.23104 would be entered as 1.23E4. Selected Answer: 2.07E0 Response The product M1V1, where the values represent the molarity of the solution delivered and the volume of Feedback: the solution delivered, represents the moles of solute delivered. The product M2V2, where the values represent the molarity of the final solution and the volume of the final solution, represents the moles of solute in the final mix. The number of moles does not change, so M1V1=M2V2, Here, you are solving for M2. Note that you can use any units for volumes, as long as you are consistent. You can use mL for both V1 and V2, or you can use L for both. You do not need to convert aything into liters. 1mL=1000L. Enter the following data into Excel and generate an xy plot. Fit a linear regression ("trendline") to the data, displaying the equation of the line. What is the line's y-intercept? Enter the value to two decimal places. DO NOT ASSUME THAT THE Y-INTERCEPT IS THE SAME AS THE Y-VALUE AT X=0 ! Selected Answer: 0.97 Response For this data set, you should get a y-intercept in the 0.3-0.5 range. Feedback: If your intercept is much above this, you may have your x and y values reversed, or you may have reported the slope rather than the intercept. Note: The program allows an error of about 0.01 for the intercept value, so as long as your reported the slope to 3 decimal places, values within normal roundoff should be fine. For each of the following prefixes, enter the corresponding power of 10 , e.g., for "d" (deca), enter "- 1 " (without the quotes) because d indicates 101. c: [A] : [B] m: [C] k: [D] n : [E] M: [F]
