A 50ml Sample of gas exerts a pressure of 4500 torr at 35C . What is the final volume at STP.

Question

This is some chemistry homework and I dont understand how to do it. Nobody in my family has any clue to do it or figure it out

Answer 1

Learn the gas laws, and these will be easy.

What you know:

Initial Volume (V1) = 50 ml = 0.05 L

Initial Pressure (P1) = 4500 torr

Initial Temperature (T1)= 35C + 273 = 308K

STP means standard Temperature and Pressure which is

T2 = 273K

P2 = 760 torr

So, now use the combined gas law:

P1V1/T1 = P2V2/T2

Substitute the values and solve for V2:

(4500)(0.05)/308 = (760)(V2)/273
