a sample of gas occupies 1.55L at 27degrees C and 2 atm pressure, what will the volume be if the pressure increased to 10.5atm and the temo is remaining constant.

how is the question set up?

A.1.55L (300K) = 2atm *V2
B.1.55L (10.5atm) = 2atm * V2
C. 1.55L *V2 = 2atm(300K)
D.1.55L (2atm) = 10.5atm * V2

.sam. · Answer

Ideal gas, assume that n is constant 
PV=nRT

(10.5)(V2)=2(1.55)

You understand it? 
Its actually 
$$P_1V_1=P_2V_2$$

You don't really need the temperature
