Answer:
Explanation:
A = Absorbance of solution
E = Molar absorptivity
l = Length of cuvette = 1 cm
c = Concentration of solution
Beer's law is given by
The equation of a straight line is given by
Comparing the above equations we get
Value on 
axis = A = Absorbance of solution = 0.23
= Slope of line = El = Molar absorptivity multiplied with length = 
= Value of x axis = c = Concentration of solution
So we get
The molar concentration of the sample is
Yes, 50 pennies plus 50 pennies equals 100 pennies minus 50pennies equals 50 pennies.

The coefficients in a balanced chemical equation are important because they give the ratio of the reactants and the products.
Those ratios are fixed and when the reagents react do it in the same proportion and yield the products in the same proportion of the coefficients.
Then, the coefficients are the basis for the calculations of the amount of substances that react and the amount of substances that are formed as result of the reaction.
