Always carbon and almost always hydrogen.
Chloroform is not a cell. it is a organic compound.

Coal is a mixture of organic compounds, mainly carbon, along with traces of other elements like hydrogen, sulfur, and nitrogen.
The molar mass of a compound is the sum of atomic weights of elements in the molecule.
If you can't find it in the literature it can be determined experimentally by titration.

Yes, empirical formulas provide the simplest ratio of elements in a compound. By determining the molar ratios between different elements in a compound, we can find the simplest whole number ratio that represents the elements present.
Carbon Monoxide is a compound. there is a easy way to find this out. An element has two sides, which is pure element and compound. pure element is substances you can easily find by searching thee periodic table of elements. If it's not on the table, it is compound or mixture. Compound is mixture of two elements and if more than three elements are mixed together, then is called mixture.
Melting point is important in organic chemistry because it can be used for the identification of a compound. For pure solid organic compounds will have a small melting point range (0.5-10C),thus presence of impurity can also be find out by Melting point.
To calculate the required volume of the organic solvent for a 90 percent separation in one extraction, you need to first find out how much of the organic compound will stay in water after extraction. Since 10% of the compound will remain in water after the extraction (due to 90% separation), the mass of the compound that will remain in water is 0.1 * 2.7g = 0.27g. If 2.7g of the compound dissolves in 100 ml of water, then 0.27g will dissolve in 100/10 = 10 ml of water. Therefore, the remaining 90% of the compound (2.43g) needs to dissolve in the organic solvent, so we consider a partition coefficient to find the volume of the organic solvent needed.
To determine the empirical formula of a compound, one must find the simplest whole number ratio of the elements present in the compound. This can be done by analyzing the mass percentages of each element in the compound and converting them to moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. This ratio represents the empirical formula of the compound.
It is a compound because iron and sulfur are two individual elements that you can find on the periodic table.
