A sample of Kr gas has a volume of 465 mL at 286°C and 844 torr. When the gas is cooled by 38.3°C, its volume is reduced by 0.572 mL. What is the final pressure of the gas in kPa?
the answer is supposed to be 105 but i keep getting 49.9!!!!!!
I tried it and obtained 105 kPa, too. Post your work and I'll try to find the error.
