Using the ideal gas law, PV = nRT, we can rearrange it to solve for density:
density = (P * M) / (R * T), where P is pressure, M is molar mass, R is the gas constant, and T is temperature.
First, we need to find the molar mass of chlorine, which is 35.5 g/mol.
Then, we can plug in the values and solve for density:
density = (1.21 atm * 35.5 g/mol) / (0.0821 L*atm/mol*K * 307.05 K) = 3.39 g/L, which is answer choice E.
