Question

Assuming that A is 0.256, ε (L/mole-cm) is 14 500, b (cm) is 1.00, molecular weight is 300 g/mole and the density of the solution is 1.00 g/mL, what is its %T? What is the value of c (Molarity) and c (ppm)?

Expert Solution

Step 1

$\begin{array}{rcl} G i v e n d a t a, \\ A b s o r b a n c e (A) & = & 0.256 \\ M o l a r a b s o r p t i v i t y c o e f f i c i e n t (ε) & = & 14500 L / m o l e . c m \\ L e n g t h (b) & = & 1.00 c m \\ M o l e c u l a r w e i g h t & = & 300 g / m o l \end{array}$
