2. Empirical formulas A compound X contains carbon, hydrogen and oxygen only. A sample of X of mass 1.56 g is found to contain 0.585 g of carbon and 0.195 g of hydrogen a) Calculate the mass of oxygen in compound X b) Complete the table that shows masses being changed to moles. la data: C. 12, H-10-16 Royal Society of Chemistry Paco 2013 Registered charity number 207800 Carbon Hydrogen Oxygen Mass of element in 9 Molos of element Simplest whole number ratio (divide each number by the smallest amount of moles) So the simplest formula for Xis: c) of the relative molecular mass of X is 32, calculate the molecular formula for X Show your working d) Draw a possible structure for molecule X
