Explanation:
<span>Answer<span>1. A certain mass of gas in a 2.00 L container has a pressure of 164 kPa. Calculate the new pressure of the gas if the volume of the container is reduced to 1.00L</span></span>
PV = nRTP is pressure, V is volume in L, n is number of moles, R is the gas constant,and T is temperature in K
(1.5 atm)(1 L) = (n)(.08206)(301K)
n = .06 moles in one liter
If there are 3.9 grams in .06 moles then
1/.06 x 3.9 = 64.2 grams per mol
