The estimated density of water (in units g/mL) at the above temperature was found using aPart 2-Volume MeasurementsThe temperature of the water was measured in °C using a thermometer: 21.9 Cstandard reference table from the Handbook of Chemistry and Physics: 0.997792 g/m.The mass of 25 mL of water was measured on the apalytical balance using three different types ofglassware. The data collected is summarized in the table below.Glassware used toVolume of WaterPercent Errordeliver 25 mL of waterMass of water (g)(mL)50 mL beaker23.497150 mL graduated cylinder25.691825 mL volumetric pipette24.8276Calculations (3 pts)Using the mass of water delivered by each method (i.e., beaker, graduated cylinder, pipette) ANDthe density of water estimated from the temperature, calculate the volume of water using theformula D = m/V, Fill in your calculated volumes in the table above. Make sure you use thecorrect mumber of sig figs!For each type of glassware, calculate the percent error by comparing the calculated volume to anaccepted value of 25.00 mL, Record your percent error in the final column of the table above.Report your answer to the nearest 0,1%2. Why did you calculate the volume of water the using the density equation? In other words, why is thecalculated volume more accurate than the measured volume? (2 pts)

Downvoted for wrong solution. A river is carrying water containing 2000 mg/l Magnesium Chloride into a small lake. The lake has a naturally occurring Magnesium Chloride of 50 mg/l. If the river flow is 2500 Lmin and the lake flow rate is 1.5 m³.sec¹, what is the concentration of MgCl2 in the lake after the discharge point? Assume that the flows in the river and lake are completely mixed, that the salt is a conservative substance, and the system is at steady state.
