Imagine that you performed this experiment as described in your lab manual. In doing so, your first temperature reading was 32℃ , and your second reading was 54℃. Your first volume was 21 mL . what would be your calculated 2nd volume?
According to Boyle's law:
V1/T1 = V2/T2
Where V1 and V2 are the first and second volumes.
T1 and T2 are the first and second absolute temperatures (in kelvin)
i.e. 21 mL/(32+273) K = V2/(54+273) K
Therefore, the second volume (V2) = 22.5 mL

a) If the specific heat of methanol is 2.51 J/K-g, how many joules are necessary to raise the temperature of 87 g of methanol from 4 oC to 99 oC ? b When a 3.78 g sample of solid sodium hydroxide was dissolved in a calorimeter in 150.0 g of water, the temperature rose from 14.5 oC to 45.2 oC . Calculate ΔH (in kJ/mol NaOH) for the following solution process: NaOH(s)→Na+(aq)+OH−(aq) Assume that it’s a perfect calorimeter and that the specific heat of...
You have set up the apparatus for this experiment, as described in the lab manual, and collected the following data: Atmospheric pressure 728.Otorr Temperature 25.8°C Gas constant 0.08206 L'atm/mol K You then ran the experiment using 0.3234 g of alka-seltzer and generated a volume of CO2 of 40.16 mL. How many moles of CO2 were produced? (Note: Don't forget to subtract the water vapor pressure from the total atmospheric pressure) 5.5X10^-4 mol of carbon dioxide 1.55X10^-3 mol of carbon dioxide...
A student performed the experiment described in this module, using 4.00 mL of a 3.5% H2O2 solution with a density of 1.61 g ml-1. The water temperature was 25 °C, and the barometric pressure in the laboratory was 30.40 in. Hg. After the student immersed the yeast in the peroxide solution, she collected 79.20 mL of O2. (5) Convert the volume, in liters, that the collected O2 would occupy at STP.
2) A professor wanted to set up a similar experiment as the one you performed in lab. He wanted to use Al(OH)3 in place of Ca(OH)2. Calculate how many mL of saturated Al(OH)3 solution it would take to titrate against 12.00 mL of 0.0542 M HCl solution. The Ksp of Al(OH)3 is 3.0x10-34. Show your work to receive credit. Finally, do you think this would be reasonable experiment for a general chemistry lab? 3) One lab section accidentally used Ba(OH)2...
