Thus, benzene is represented by the empirical formula CH, which indicates that a typical sample of the compound contains one atom of carbon (C) to one atom of hydrogen (H).
Look at the mass percent as the mass of each element in a 100 g sample of the compound.
American officials have said that although Dr. Afridi never gained DNA samples from the compound, his work aided the mission that led to Bin Laden's death.
The C.I.A. has admitted hiring a Pakistani doctor to give out hepatitis B vaccine, apparently in an effort to get DNA samples from the compound that it suspected was Bin Laden's hide-out.

Afterwards, the wear rate stabilized, but it was higher than that measured on the nitride samples without the compound layer.
However, injection molded test samples of the compound showed higher elongation at break and lower modulus and stress at break in comparison to the virgin material.
In every sample the 50 compounds with the highest concentrations were reported as Toluene-equivalents.
The fiber was exposed to the vapor phase for 5 min to sample the volatile compounds, and then inserted into the injection port of the GC-MS (GC QP 20120, Shimadzu) using an inlet liner (0.75 mm i.d).
We used the GSVM-RU method to sample the inactive compounds based on their significance to the classification.
