An organic acid is composed of carbon (58.80%), hydrogen (9.89%), and oxygen (31.33%). Its molar mass is 102.13 g/mol. Determine the molecular formula of the compound.
Mintlactone is a compound found in peppermint that is composed of carbon, hydrogen, and oxygen. When 1.000 gram of mintlactone undergo complete combustion in the presence of oxygen, 2.648 grams of carbon dioxide and 0.7587 grams of water are produced. Given that the molar mass of mintlactone is 166.2 g/mol, (i) determine its molecular formula.
A gaseous compound composed of carbon nitrogen and hydrogen in a vessel at 380.4 K and 0.928 bar has a density 1.8228 g L-1. By burning a sample of that same gas it is determined that it is composed of 38.67% C and 16.22% H. What is the molecular formula of the compound expressed as a string CxHyNz. Do not use subscript underscores of curly brackets when entering the formula.
