C.4 Valinomycin is an antibiotic that has been used to treat tuberculosis. Valinomycin contains atoms of carbon, hydrogen, nitrogen, and oxygen in the ratio 9 15 1 3. Its molecules each have 18 oxygen atoms. Write the chemical formula of valinomycin. 

The index of hydrogen deficiency can be calculated for compounds containing carbon, hydrogen, nitrogen, halogen, oxygen, and sulfur from the formula... 

Organic chemicals or compounds Naturally occurring (animal-, plant-produced, or synthetic) substances containing mainly carbon, hydrogen, nitrogen, and oxygen. 

Exact masses and corresponding formulae for various possible ions of m/z 180 containing only carbon, hydrogen, nitrogen and oxygen atoms in limited number (C6-U, H0 24, Nq-4 and O0-4). 

A compound contains only carbon, hydrogen, nitrogen, and oxygen. Combustion of 0.157 g of the. compound produced 0.213 g of C02 and 0.0310 g of H20. In another experiment, 0.103 g of the compound produced 0.0230 g of NH3. What is the empirical formula of the compound Hint Combustion involves reacting with excess 02. Assume that all the carbon ends up in C02 and all the hydrogen ends up in H20. Also assume that all the nitrogen ends up in the NH3 in the second experiment. 

To illustrate, the molecular ion of a compound was measured with an accuracy of 0.001 Da (a typical accuracy) to be 146.0738. Table 3.1 contains all possible combinations of carbon, hydrogen, nitrogen, and oxygen (with a maximum of six nitrogen or oxygen atoms) for an ion of nominal mass 146. 

Researchers obtained the following data from experiments to find the molecular formula of benzocaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 3.54 g sample of benzocaine with excess O2 formed 8.49 g of CO2 and 2.14 g H2O. 

NG is found to consist mainly of the lightweight alkanes, with varying quantities of carbon dioxide, carbon monoxide, hydrogen, nitrogen and oxygen, in some cases also hydrogen sulfide and possibly ammonia. A typical sample of NG when it is collected at its source contains 80% methane (CH ), 7% ethane (C Hj), 6% propane (CjHj), 4% butane and isobutane (C Hj ), and 3% pentane (CgHj ). 

Except the protamines, the histones and the derivatives of the proteins, all the proteins contain carbon, hydrogen, nitrogen, sulphur and oxygen, and they possess the following elementary composition —...
