P1v1/t1 = p2v2/t2
<span>
0.9atm ( 50ml)/298K = 1atm x (v) / 273 </span>
<span>solve for v </span>
<span>0.9 x 50 x 273 /298 x 1= v </span>
<span>v = 41.2 ml</span>
We first assume that the gas is ideal which is a safe assumption to approximate the answer to the problem. Then we need to know the ideal gas equation and that is:
PV=nRT
where
P- pressure
V- volume
n-number of moles-
R- ideal gas constant
T-temperature.
Since we know that P, T and V are constant, rearranging the equation would lead to:
P/TR = n/V or the ratio of the moles of gas and volume is constant.
(3moles)/2L = (3+x)/4L
where
x is the additional moles.
Solving for x = 3 moles.
