A murexide soution has a concentration of 3.52x10-4M and an absorbance of 1.850. what is the molar absorptivity of the solution?

The question is incomplete, here is the complete question:

A murexide soution has a concentration of and an absorbance of 1.850 and the path length is 1 cm. What is the molar absorptivity of the solution?

The molar absorptivity coefficient is

Explanation:

To calculate the molar absorptivity coefficient, we use the equation given by Beer-Lambert law, which is:

where,

A = absorbance = 1.850

= molar absorptivity coefficient = ?

C = concentration of the solution =

l = path length = 1 cm

Putting values in above equation, we get:

Hence, the molar absorptivity coefficient is

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles
