A typical fluorescent light bulb contains argon gas and mercury vapor.?
a. If the total gas pressure in a fluorescent light bulb is 307.1 Pa and the partial pressure of the argon gas is 306.0 Pa, what is the partial pressure of the mercury vapor?
b. If a 935-mL fluorescent bulb contains 4108 mg of argon gas and 77 mg of mercury vapor, what is the total gas pressure in the fluorescent bulb at 313 K?

a. Ptotal = pHg + pAr
b. mols Ar gas = grams/molar mass = ?
mols Hg gas = grams/molar mass = ?
Total mols gas = nHg + nAr
Then use PV = nRT and solve for P at the conditions listed. Remember V is in L.
