At the end of the experiment a student spill some hcl solution as he pours it from the baby bottle to the preweighed 150mL beaker. He determines the final mass of the HCl beaker and solution ignoring the spilled solution. Would his calculated R value be too high or too low? Explain Why

Calculate value of R for 1.00 mole of gas having a volume of 22,400mL at 760.mm and 273K in units of mL X mm / mol X K. Show Work

The ideal gas law is:


PV=nRT


You have been given values for P (pressure), V (volume), n (number of moles of gas) and T (temp in kelvins), so you can calculate R by rearranging the formula:


R = PV/nT.
