Explanation:
In order to find the relative molecular mass of a liquid hydrocarbon, X, the liquid was injected into a syringe oven that was kept at a temperature of 100 °C. After vaporisation of the injected liquid it was found that 0.172 g of liquid produced 61.4 cm3 of vapour. The pressure was 1.01 × 105 Pa and the universal gas constant is 8.314 J K–1.
a) Calculate the relative atomic mass of hydrocarbon.
b) When 20 dm³ of the vapour of X is burned in oxygen, 120 cm³ of carbondioxide were produced. Calculate the number of carbons in a molecule of X and hence find the molecular formula of X
