The absorbance of a crystal violet solution in water (density is 1.00 g/ml) is measured in a 1.0 cm cuvette. the absorbance is 0.614 and the molar absorptivity coefficient is the molecular weight of crystal violet is 407.98 g/mol. what is the molar concentration of the solution?

Answer : The molar concentration of solution is

Explanation :

Using Beer-Lambert's law :

where,

A = absorbance of solution  = 0.614

C = molar concentration of solution = ?

l = path length = 1.0 cm

= molar absorptivity coefficient =   (assume)

Now put all the given values in the above formula, we get:

Therefore, the molar concentration of solution is

diaria maybe go see a doctor about that

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
