In an experiment to calibrate a 50 ml burette at 30 ⁰C, a student calculated the volume corrections for a series of volumes delivered by the burette and recorded the following data 1. Plot a graph of volume corrections against apparent volumes and briefly describe the nature of the graph 2. If a student used this burette to measure 45ml of water at 30⁰C, what will be the true volume of water delivered at this temperature

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.

Copy Data Table 3 into Excel. Use Excel to create a graph with Pressure (in atm) on the horizontal axis (the independent variable) and Temperature (in kelvins) on the vertical axis (the dependent variable). Set the scale on each of the axes to show O Kand O atm. Draw the best straight line that goes through most of the points and extrapolate (extend) the line until it goes through O atm. Copy and paste the graph at the bottom of this document. Does the graph show that Pis proportional to Tas stated by Amonton's and Gay-Lussac's Law? a. Absolute zero is OK. What is the temperature reading when the extrapolated line goes through o atm? Considering what is now known about Amonton's and Gay-Lussac's Law, make a prediction based on the…
A.) A sample of argon gas at a pressure of 0.831 atm and a temperature of 223 degrees Celsius, occupies a volume of 530 mL. If the gas is heated at constant pressure until it’s volume is 782 mL, the temperature of the gas sample will be ____degrees Celsius. B.) A sample of helium gas at a pressure of 973 mm Hg and a temperature of 55 degrees Celsius, occupies a volume of 8.29 liters. If the gas is heated at a constant pressure to a temperature of 78 degrees Celsius, the volume of the gas sample will be ____L.
What is w when the volume of a gas expands from 24.7 L to 29.2 L against a constant external pressure of 801 Torr? Remember to include a "+" or "-" sign as appropriate. Note: 760 Torr = 1 atm = 1.01325 bar = 101.325 kPa Enter your answer in acceptable SI units, accurate to 3 significant figures. Use an acceptable Sl symbol for units. Number Units
