Suppose you have a deck of 40 cards, containing 10 red cards and 30 black cards. A player draws 7 cards from the deck and places them into their hand. The remaining deck of 33 cards has 5 red cards and 5 black cards in the top 10 cards. The other 23 cards in the remaining deck are unknown color. What is the probability of the player's hand having 0,1,2,3,4,5 red cards?

Erioglucine is a blue­colored dye that absorbs its complementary color, red, in aqueous solution around 645 nm. Unfortunately, the local distilled water supply is consistently contaminated with a trace amount of a metal cation that also absorbs 645 nm light. Suppose then, a control sample of 0.0552 M erioglucine (aq; same water supply) has an absorbance of 0.331 and that a distilled water sample in a similar cuvette has an absorbance of 0.019. Determine the concentration of an erioglucine (aq)...

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?

6. For an 8x10-5M methyl red solution at pH 5, A525nm is 0.92. (1cm cells were used to make this measurement.) The experimenters ascertained the following two facts about this chemical system: (1) At 525nm, absorbance by MER- is negligible, and (2) Molar absorptivity at 525nm for HMER is 23,000. What is the dissociation constant for the dye methyl red? (pKa is between 4 and 6).

3a. If the molar absorptivity constant for the red dye solution is 5.56×104 M-1 cm-1 , calculate the molarity of the red dye solution with absorption = 0.900. You may assume L = 1.22cm. Hint: A=εLC b. Convert the molarity in part a to w/v%. Show your work. Molar mass of FD&C red #3 = 879.86g/mol w/v% is defined as weight (in grams) of solute/100 mL of solution You should remember that w/v% always refers to the grams of materials...
