10. Samples of a new anticancer drug in aqueous solution were stored at 45°C, 60°C and 75°C. The first-order rate constants for the decomposition at different temperatures were determined as follows: 45 60 75 Temperature (°C) Rate Constant (day'') 0.052 0.069 0.089 Considering that the drug expires once the concentration decreases to 90% of the original, calculate the expiration time of the anticancer drug at 25°C (room temperature).

Biology Lah 10. (20) You are setting up an experiment to electroporate AX2 cells with a new vector. The vector has a Belomycin resistance marker gene. The literature tells you that Bleomycin is effective on dicty in a concentration range of 1-50 μg/ml in HL-5 media and cells die after 1-5 days. Your boss tells you that you need to determine the best concentration of Bleomycin to kill Dicty before you begin your electroporation experiment. How would you set up...

In lab you carried out a serial dilution and calculated the concentration of each solution. Starting with a 2.05 M HCl stock solution, three standard solutions are prepared by sequentially diluting 5.00 mL of each solution to 150.0 mL. What is the concentration of the final solution? 0.0683 M 2.28 times 10^-3 M 9.11 times 10^-6 M 7.59 times 10^-5 M 2.53 times 10^-6 M

A student made solution #3 using the experimental method in this
lab, and measured an absorbance of 0.559. The starting reagents are
2.00 x 10-3 M Fe(NO3)3 and 2.00 x
10-3 M KSCN.
The amount of absorption is proportional to the concentration
of
FeSCN2+. This relationship – true for many solutions – is called
“Beer’s Law”, and has the simple equation:
A = bc
where “A” is the absorption, “b” is 5174.6 for FeSCN2+ and “c”
is molarity
