CHEMISTRY URGENT!

a sample of oxygen that occupies 1.00 x 10^6mL at 575mmHg is subjected to a pressure of 1025atm. what will the final volume of the sample be if the temperature is held constant?
how do uu set up the equation

P1V1 = P2V2

just one question how do you find the constant k???

There may be as many as 1000 constants ( or more). Which k do you want?

for combined gas law

Actually, it is never necessary to calculate k. If
(P1V1/T1) = k and
(P2V2/T2) = k, then
(P1V1/T1) = (P2V2/T2)
To answer your question, however, you calculate k from (P1V1/T1) = k
