Abeer's law plot for cu2+ was experimentally obtained. the slope of the beer's law plot was 310 l/mol (with a y-intercept = 0.001). a cu2+ solution of unknown concentration had an absorbance of 0.55. what is the molar concentration of cu2+ in the unknown solution?

is the molar concentration of Cu(II) ions in the unknown solution.

Explanation:

Using Beer-Lambert's law :

Formula used :

where,

A = absorbance of solution

C = concentration of solution

l = length of the cell =

= molar absorptivity of solution

A Beer's law plot is between absorbance and concentration.

We have:

A = 0.55

The slope of the Beer's law plot = m = 310 L/mol

So, the concentration of the solution is:

is the molar concentration of Cu(II) ions in the unknown solution.

answersilicon (si); oxygen (o);

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
