You are checking the accuracy of a volumetric flask marked 10.00 mL. Tocalculate the volume of water contained in the flask, you first measure the mass ofthe 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.MeasurementVolume (mL)110.059210.0503.10.009410.062Calculate the mean and the 95% confidence interval for these measurements.10.0256.10.01910.0498.10.020ml.10.036mean:10.021mL95% confidence interval: +Incorrect

107 A soft drink can’s label indicates that the volume of the soda it contains is 12 oz or 355 mL. There is probably some empty space at the top of the can. Describe what you can measure and how that measurement allows you to determine the actual density of the soda.
The solubility of oxygen gas in water is approximately 0.00489 g/L. when the temperature is 25.0°C and the partial pressure of gaseous oxygen is 769.4 torr. What will the solubility of oxygen (in g/L) be if the oxygen pressure is adjusted to 963.5 torr? Do not write unit in answer. Report your answer with the correct sig figs, don't use scientific notation. Type your answer...
A student constructs a simple constant volume gas thermometer and calibrates it using the boiling point of water, 100°C, and the freezing point of a specific brine solution, -17°C. The pressures measured at the calibration points are 1.366 atm and 0.9267 atm, respectively. **when explaining please use math symbols & equations rather than typing it out, gets confusing if something is in a fraction or whatnot. Thank you!
A certain substance X has a normal boiling point of 131.9°C and a molal boiling point elevation constant =Kb·1.78°C·kgmol−1. A solution is prepared by dissolving some urea ((NH2)2 CO) in 600.g of X. This solution boils at 133.7°C. Calculate the mass of urea that was dissolved. Round your answer to 2 significant digits.

Round everything to four decimal places and box all final answers. All values must include proper units with proper conversion if needed in your solution. 1.0 L of liquid nitrogen is kept in a closet measuring 10.0 dm by 1x10-12 Tm by 2x1024 ym. Assuming that the container is completely full, that the temperature is 25.0 °C, and that the atmospheric pressure is 1.0 atm, calculate the percent (by volume) of air that would be displaced if all the liquid nitrogen evaporated. (Liquid nitrogen has a density of 0.807 g/mL.)
In a separate experiment, a student determines the vapor pressure of water to be 34.592 at 30°C. What is the percent error in the experimental value of Pwater, using the tabulated value at the experimental temperature as the accepted value? Report your answer as a percentage to 4 significant figures.
