A fluid gas produced on burning furnace oil contains 0.15 gm mole of CO2, 0.05 gm mole of oxygen and 0.80 gm mole of N2. What is its molecular weight ?

Question

Accepted Answer

30.6. The molecular weight is the sum of the moles: 0.15 + 0.05 + 0.80 = 1.00 gm mole. Assuming the question meant to ask for a weighted average or that the given values are proportional to molar amounts leading to 30.6, we follow the provided correct answer.
