Why is carbon dioxide heavier than nitrogen?
The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
A compound contains only carbon hydrogen nitrogen and oxygen combustion of 0.157g of the compound produced 0.213g CO2 and 0.0310g H2O In another experiment it is found that 0.103g of the compound?
Molar masses: C = 12 g/mol O = 16 g/mol H = 1 g/mol N = 14 g/mol CO2 = 44 g/mol H2O = 18 g/mol NH3 = 17 g/mol * 44 g CO2 is produced from 12 g C 0.213 g CO2 is produced from = (12)(0.213) / 44 = 0.0581 g C present in 0.157 g compound. * 18 g H2O is produced from 2 g H 0.0310 g H2O is produced from = (2)(0.0310) / 18 = 0.0034 g H present in 0.157 g compound. * 17 g NH3 is produced from 14 g N 0.0230 g NH3 is produced from = (14)(0.0230) / 17 = 0.0189 g N present in 0.103 g compound.(this is different) If in 0.103 g compound there is 0.0189 g N in 0.157 g compound there is ; (0.157)(0.0189) / 0.103 = 0.0288 g N * Mass of C, H and N = 0.0581 + 0.0034 + 0.0288 = 0.0903 g The rest is mass of O = 0.157 - 0.0903 = 0.0667 g Moles of elements in the compound sample: C = 0.0581 g / 12 g/mol = 0.00484 mol H = 0.0034 g / 1 g/mol = 0.0034 mol N = 0.0288 g / 14 g/mol = 0.00205 mol O = 0.0667 g / 16 g/mol = 0.00417 mol Smallest mole ratio: N = 0.00205 / 0.00205 = 1.00 C = 0.00484 / 0.00205 = 2.36 H = 0.0034 / 0.00205 = 1.66 O = 0.00417 / 0.00205 = 2.00 Multiplying by 3 we get; N = 3 C = 7 H = 5 O = 6 Simplest formula: C7H5O6N3
