Question

Question 9: If b= (1.000x10^0) , c= (2.10x10^-3) , A= (5.5800x10^-1) what is the molar absorbtivity 'a'?

( When entering answers in scientific notation 0.00100 would be 1.00e-3 )

Question 10: Transmittance is defined as the fraction of the original light that passes through the sample. T=P/Po where Po is the original and P is after passing though the cell. You will measure T on the instruments. A=log10(Po/P)= -log T or 2.00-log(%T) or abs. If %T = 67 % what is A?

T=P/Po where Po is the original and Pis after passing though the cell. You will measure T on the instruments. A=log10(Po/P)= -log T or 2.00-log(%T) or abs. If %T = 67 % what is A? Your Answer: Answer

Answer 1

Q-9. A= Ebc E= A 1. bc = 5.5800 x 100 1.000 x 10° x 2.10X10-3 = 5.5800 x 10-3+3 1.000 x 2.10 = 5.5800 x 102 -= 265.714 2.10 = 12,6571x102 Q-10 A = 2.00 - 109(77) =2.00-log (67) = 2.00 – 11826 = 0.1739 A = 0.174
