Calculate the molar mass of copper(II) carbonate. View Solution A compound X consists of 4.8% carbon and 95.2% bromine by mass. If the vapour density of the compound is 252, what is the molecular formula of the
molecular formula of the compound. The molecular mass of a compound is calculated from the atomic masses of the various elements present in the compound. The percentage of mass of each element is then calculated with the help of the following relation. Percentage mass of the element in the ...

The greater number of atoms of either one of the given elements has to be interpreted. Concept Introduction : The element symbol : Z A X, where, A (mass number) = no .of protons + no .of neutrons . Z (atomic number) = no . of protons . ...
The short thermal stability of all investigated DESs is strictly related to the HBD used. EG-based DESs were less stable than LevA-based ones while Gly-based DESs were the most stable materials. Moreover, for all DESs three characteristic mass loss events have been identified. They can be ...
