You make two dilutions. You take 82.19 mL of the stock solution (8.1×10^-5M) and dilute to 500.0 mL to make Solution #1. You then add 66.26 mL of Solution #1 to 30.11 mL of water to make Solution #2.

What is the concentration of the Solution #1 in terms of molarity?

What is the concentration of the Solution #2 in terms of molarity?

1) You have 100 ml of a solution of ATP. You take 25 ?l, and dilute it to a final volume of 1ml. The absorbance of the diluted solution at 259 nm is 0.550. a) What is the ATP concentration in the original, undiluted solution? **The molar extinction coefficient for ATP at 259 nm is 15,600 l mol-1cm-1. b. How many mg of ATP are there in total in the original, undiluted solution? **The formula weight of ATP is 551.14...

You mixed 600 mL of 5M NaCl and 150 mL of sodium citrate solution and added 250 mL of water to make a 1L stock 20X SSC (standard sodium citrate) buffer. With 40 grams of SDS, sodium dodecyl sulfate you made 800 mL of a 5% SDS solution. ~Calculate how much SDS and SSC you need from the above solutions to make 1 Liter of 0.1X SSC, 0.1% SDS.

You decide to dilute a broth culture by making a series of four 1:100 dilutions. You then pipet 1 ml of the final dilution onto one agar plate and 0.1 ml onto a second plate. After incubating overnight, you count 350 colonies on the first plate (with 1 ml) and 56 colonies on the second plate (with 0.1 ml). Which plate would you use for your calculations? Why? Calculate the concentration of the original culture and be sure to include...
