What is the empirical formula for a compound if 300. 00 g of it is known to contain 82. 46224 g of molybdenum, 45. 741 g of chlo
1 answer:
the empirical formula for a compound is Mo2Br5Cl3.
The empirical components of a compound are the best entire quantity ratio of atoms of every detail within the compound. it's miles decided using statistics from experiments and therefore empirical. as an example, the molecular formula of glucose is C 6H 12O 6 however the empirical formulation is CH 2O.
An Empirical formula is the chemical components of a compound that offers the proportions (ratios) of the elements present in the compound however no longer the real numbers or arrangement of atoms. This will be the lowest complete range ratio of the elements within the compound.
The empirical method of a compound gives the only ratio of the range of various atoms gift, while the molecular formula gives the actual range of each distinctive atom found in a molecule. If the components is simplified then it is an empirical components.

Explanation:
Relation between pressure, latent heat of fusion, and change in volume is as follows.
Also,
where, is the difference in specific volumes.
Hence,
As, = 22.0 J/mol K
And, ...... (1)
where, = density of water
= density of ice
M = molar mass of water =
Therefore, using formula in equation (1) we will calculate the volume of fusion as follows.
=
=
Therefore, calculate the required pressure as follows.
=
or, = 145 bar/K
Hence, for change of 1 degree pressure the decrease is 145 bar and for 4.7 degree change dP =
= 681.5 bar
Thus, we can conclude that pressure should be increased by 681.5 bar to cause 4.7 degree change in melting point.
