Question

What mass, in grams, of fluorine has (F2) is contained in a 10.3-liter tank at 29.8 degrees Celsius and 1.23 atmospheres? Show all of the work used to solve this problem.

Answer 1

PV = nRT
P is pressure, V is volume in L, n is number of moles, R is the gas constant, and T is temperature in K

(1.23 atm)(10.3 L) = (n)(.08206)(29.8 + 273)

n = .5 moles x 38 grams per mol F2 = 19.4 grams F2
