The molar absorptivity of Beta-carotene at 490 nm is 1.36 x 105 M-1cm-1. What is the concentration of a solution of Beta-caroten
finlep [7]

Answer:

The correct answer to the following question will be Option E (1.0 x 10⁻³ M).

Explanation:

The given values are:

A\lambda =140

\varepsilon=1.36\times 10^5 \ M \ {cm^{-1}}

L = 1 \ cm

As we know,

⇒  A\lambda=\varepsilon CL

On putting the given values in the above formula, we get

⇒  140=1.36\times 10^5\times C\times 1

⇒  C=\frac{140}{1.36\times 10^5}

⇒  C=102.9\times 10^{-5} \ M

So that option E is the right answer.

stira [4]
<span>The question says.'which option describes a similarity between isotopes of an element. The correct option is C. Isotopes have the same number of atomic number but different mass number. The mass number is the summation of proton and neutron. The number of proton is always constant but that of neutron changes to reflect the existence of isotopes.</span>
