P1V1/T1=P2V2/T2 combined gas law 1.0atm*0.50L/298K=5.0atm*0.50L/T2 Can you help me to go from this step to the solution?
How many pounds of propane,C3H8, if you pay $20 for a 15L cylinder, filled to 150 psi at 25 degrees C.
Calculate temperature when 0.50L sample or gas at 1.0 atm and 25degrees C is compressed to 0.05L of gas at 5.0 atm.
The previous questions that I submitted are still unclear to me as a plug and chug approach does not help me at all. Can you please explain better?
The hydornium ion concentration in blood of three different patiens was: Patient [H30+] A 5.0 X 10^-8 B 3.1 X 10^-8 C 3.2 X 10^-8 What is the pH of each patient's blood? If the normal range is 7.30-7.50, which, if any, of these patient's have an abnormal blood pH?
Calculate both [H30] and [OH-] for a solution that is: pH=5.50 ph=7.00
Calculate [H3O] for a solution of hydrochloric acid that is: pH=2.00 pH=3.00
