Empirical and Molecular Formula: The actual ratio among all elements comprising a compound is represented by writing the molecular formula of that compound. Whereas, the simplest ratio among these elements is represented by its empirical formula....
Gram Molecular Mass: The gram molecular mass is the same idea as the molar mass of a substance. The periodic table lists all of the elements' molar masses. It is the average of all of the isotopes of that element. Answer and Explanation:1 ...
The molar mass of water is equivalent to the mass of one mole of water molecules. One mole is a scientific form of measurement in chemistry. Elements need to have equal amounts of protons and electrons to be stable, but they can vary in the amount of neutrons they contain. The amount ...
Molecular mass is also called molecular weight. Because the mass is relative to carbon-12, it's more correct to call the value "relative molecular mass". A related term is molar mass, which is the mass of 1 mol of a sample. Molar mass is given in units of grams. ...
Calculating the Molar Mass of a Compound: In order to calculate the molar mass of any compound, we only need to know what elements are contained in the compound and what the molar mass of the elements are. Answer and Explanation:
Alginates are linear anionic polysaccharides, present in the cell wall; fucans are high molecular weight polysaccharides of brown algae known to contain L-fucose as its main sugar constituent; and sulfate ester and laminarin are a linear polysaccharide with a small molecular weight (Ahmadi et al....
