Calculate the volume of buffer to which 500ml of 60 mm potassium chloride solution must be diluted to make a new concentration of 0.001m.

mL

Explanation:

Given -

Volume of buffer mL

Concentration of solution mMM

New concentration of the solution M

As we know

Where

are the concentration of the solution before and after dilution.

And are the volume of solution before and after dilution.

Substituting the given values in above equation, we get -

mL

chlorophyll a: this is the most abundant pigment in plants. chlorophyll a absorbs light with wavelengths of 430nm(blue) and 662nm(red). it reflects green light strongly so it appears green to us.
