The largest a party balloon can get before bursting is 8.55 L at 25^oC and 1.00 atm. Supposing you fill the balloon only with oxygen gas, how many grams of oxygen can be added to the balloon before it pops? Assume you have not yet added any gas to the balloon at all (so essentially the balloon is flat). A) 11.2 g O₂ B) 0.350 g O₂ C) 4.17 g O₂ D) 133 g O₂ E) 2.86 g O₂

Using the ideal gas law PV = nRT and the molar mass of oxygen (32.00 g/mol), we can calculate the mass of oxygen that can be added to the balloon. Given the volume (8.55 L), temperature (298 K, converted from 25°C), and pressure (1.00 atm), we can solve for n (moles of gas) and then convert moles to grams. The calculation yields approximately 11.2 grams of oxygen.
