The resolution calculated for the tlc separation of a two-component mixture is determined to be equal to 2.0. does the represent
1 answer:
Answer: No, it does not represent a good separation.
Explanation: Resolution is the measure of extent of separation between two components and the base-line separation. It is calculated using the formula
Where, = resolution
= Difference between the retention times of two components.
= Spot widths of two components.
The perfect resolution is considered as 100.
Here, we are given that the two components in a mixture both have a resolution at 2.0 that means both the peaks are overlapping each other and thus the components cannot be determined accurately.
Thus, this does not represent a good separation as as the two components are spotted closely.

<h3>Further explanation </h3>Graham's law: the rate of effusion of a gas is inversely proportional to the square root of its molar masses or
the effusion rates of two gases = the square root of the inverse of their molar masses:
or
From this equation shows that the greater the mass of the gas, the smaller the effusion rate of the gas and vice versa, the smaller the mass of the gas, the greater the effusion velocity.
So if both gases are at the same temperature and pressure, the above formula can apply
Answer : The mass of lithium hypochlorite are, 34.7 grams.
Explanation : Given,
Moles of = 0.594 g
Molar mass of = 58.4 g/mol
Expression used :
Now put all the given values in this expression, we get:
Therefore, the mass of lithium hypochlorite are, 34.7 grams.
