A bag of potato chips contains 585 mL of air at 25°C and a pressure of 765 mm Hg. Assuming the bag does not break, what will be its volume at the top of a mountain where the pressure is 448 mm Hg and the temperature is 6.0°C? I set it up like p1v1/t1= p2v2/t2 and got 940ml but...

is 765/2023 simplified?!!? I think it is. Nope, it isn't, 765 = 32*5*17 check the divisor of 765 into 2023 what do you mean What do you mean?Your making it more difficult for her! What am I making difficult here? All we need to do is find the factorization of one of the ...
