Answered by Christopher R - Wed Sep 23 00:10:17 2009 How to solve this chemistry problem about percent composition? Q. An herbicide is found to contain only C, H, N, and Cl. The complete combustion of a 100.0-mg sample of the herbicide in excess oxygen produces 83.16 mL of CO2 and 73.30 mL of H2O vapor at STP. A separate analysis shows that the sample also contains 16.44 mg of Cl. Determine the percent composition of the substance. Asked by cool - Thu May 14 00:10:05 2009 - - 1 Answers - 0 Comments A. This is a bit tedious, but you just have to work through it. Volume of one mole of gas at STP: 22.4 litres. Moles of CO2 produced: 83.16 / 22400 = 0.00371 One mole of C per mole of CO2 : 0.00371 12 grams per mole of C : 0.04455 grams or 44.55mg of C. Moles of H2O produced: 73.30 / 22400 = 0.00327 Two moles of H per mole of H2O : 0.00654 One gram per mole of H : 0.00654 grams or 6.54mg of H. 44.55mg of C + 6.54mg of H + 16.44 mg of Cl = 67.53 Subtract that from 100.00mg, leaves 32.47mg of N. Because the sample is 100mg, those are also the percentage compositions by weight. Just one awkward observation: how do we get 73.30 mL of H2O vapor at STP ? At STP, the water would be liquid, on the point of freezing.. Answered by WhatGoes Around Comes Around - Sun May 17 21:29:27 2009 What is the chemical composition of Helium?
Q. I'm doing this report on Helium and I need to know what the chemical composition of Helium is. Thanks for helping! Asked by JACKASS<3 - Tue Oct 6 20:26:33 2009 - - 2 Answers - 0 Comments A. Do you mean how many electrons, mass, etc? If so just look at a periodic table.
