Cyanogen is a gas which contains 46.2% C and 53.8% N by mass.At a temperature of 25°C and a pressure of 750 mm Hg,1.50 g of cyanogen occupies 0.714 L.What is the molecular formula of cyanogen? A)CN B)C₂N₂ C)C₃N₄ D)C₄N₅

Question

Quizplus · Accepted Answer

The molecular weight of cyanogen can be calculated using the ideal gas law. Using the given conditions, the molar mass is found to be approximately 52 g/mol. The empirical formula mass of CN is 26 g/mol, so the molecular formula is C₂N₂.
