A manometer was connected to a bulb containing carbon dioxide under slight pressure. The gas was allowed to escape through a small pinhole, and the time for the manometer reading to drop from 75 cm to 50 cm was 52 s. When the experiment was repeated using nitrogen (for which M = 28.02 g mol⁻¹) the same fall took place in 42 s. Calculate the molar mass of carbon dioxide.
