Answer:
 is the concentration of the compound in a solution.
 is the concentration of the compound in a solution.
Explanation:
Using Beer-Lambert's law :
Formula used :

Where:
A = absorbance of solution
C = concentration of solution 
l = path length
 = molar absorptivity coefficient
 = molar absorptivity coefficient
We have:
C = ? , l = 1.00 cm, A = 0.090



 is the concentration of the compound in a solution.

Answer:
317 g
Explanation:
Cu + 2HCl --> CuCl2 +H2
1      :     2           1 : 1
1 mole of Cu  = 63.5 g
1 mole of  H2 = 2g
1 mole  Cu produces = 1 mole of H2
63.5 g of Cu produces = 2 g of H2
So
10 g of H2 will be produced from =  (63.5/2)*10 = 317 g of Copper
