2. Using Excel, make a graph of the following data. Plot Mass vs. Volume for the following data on the same graph. Use a linear fit of each set of data and include the equation of the best fit line (2 fits and 2 equations, making sure you can tell which equation is for which set of data). Submit your graph and answer the three questions below. Volume (ml) 5.00 10.00 15.00 20.00 30.00 Mass of Al (g) 43.195 56.053 70.961 82.499 108.988 Mass of Zr (g) 63.797 94.708 127.933 158.580 227.037 For both straight lines, the slope is essentially equal to the density of the element. The y-intercept is equal to the mass of the beaker that held the substance. Answer the following questions. a) For each element, what is the density (slope)? What is the mass of the beaker (y-intercept)? Be sure to include units. b) If you have 120.000 g of Al and beaker, what is the volume? $24.0 c) When the volume of Zr is 25.00 mL, what is the mass?

In a river with a constant flow rate, the factory releases wastewater containing NaCl at a concentration of 200 mmol / L to the river at 20.0 L / s. The Na+ and Cl- concentrations at the downstream observation point were 1.00 mmol / L and 0.800 mmol / L, respectively. What is the river flow Q and Cl- concentration before the inflow of drainage? The river originally contains 0.500 mmol / L of Na+.

The level of water in a rectangular swimming pool needs to be lowered 7.00 inches. If the pool is 44.5 feet long and 15.5 feet wide, and the water is siphoned out at a rate of 5.40 gal/min (gallons per minute), how long will the siphoning take? 1 ft3 = 7.48 gal.
There is a typo in the response for Molly. Molly's original volume should be written as 8.0 L, not 8 L. Apply the significant figure rule to the final answer. Your final answer should have one significant figure. Use CER, claim is your answer, evidence is your calculation, and, reasoning is your further explanation. You can provide information about the formula you used to solve as well.

You are checking the accuracy of a volumetric flask marked 10.00 mL . To calculate the volume of water contained in the flask, you first measure the mass of the empty flask and the mass of the flask filled with water and take the difference. Then, you correct for the buoyancy factor and divide by the density of the water. The result of 8 such measurements is given in the table. Calculate the 95% confidence interval for these measurements with a mean of 10.03.
