Explanation:
Answer : The molar heat of fusion for substance X is, 775.6 cal/mol
Explanation :
First we have to calculate the moles of substance X.
Given:
Molar mass of substance X = 58.45 g/mole
Mass of substance X = 326.0 g
Now put all the given values in the above expression, we get:
Now we have to calculate the molar heat of fusion for substance X.
where,
Q = heat releases = 4325.8 cal
= molar heat of fusion for substance X = ?
n = moles = 5.577 mol
Now put all the given values in the above expression, we get:
Thus, the molar heat of fusion for substance X is, 775.6 cal/mol
Using a thin stationary phase supported by an inert backing, thin layer chromatography (TLC) is a chromatographic technique used to separate the components of a mixture.
It can be carried out on an analytical scale to track the development of a reaction or on a preparative scale to purify minute quantities of a chemical. Because of its simplicity, comparatively low cost, great sensitivity, and rapid separation, TLC is an extensively used analytical method. Similar to all chromatography, TLC works on the premise that a chemical will have varying affinities for the mobile and stationary phases, which will influence how quickly it migrates. TLC aims to produce well-defined, well-separated spots.
