Chemistry 2 Jorge Nuñez Ms. Principe / Period 2 February 8th‚ 2011 Aim: How are we going to determine the empirical formula of a compound? Do Now: 1) What is the percent by mass of oxygen in H2C2O4? H2 = 2(1) = 2 ; C2 = 2(12) = 24 ; O4 = 4(16) = 96 Gram Formula Mass = 90 Percentage of Oxygen = 6490 x 100 = 71% 2) Calculate the percentage of water: -Mass of empty crucible and cover = 11.7g -Mass of crucible‚ cover‚ and hydrate before heating = 14.9g -Mass of crucible
