← How many ethers have the molecular formula C₄H₁₀O?
A chemical store has a volume of 15 m³. A tray of ethoxyethane (molar mass 74.123 g/mol) is left open, and the liquid slowly evaporates. Ether vapour burns in air once it is 1.9 % of the volume of the air or more, and at this room temperature one mole of any vapour takes up 24.46 L. How many grams of ether must evaporate before the store air can burn? →
