The odor of skunks is caused by chemical compounds calledthiols. These compounds, of whichbutanethiol (C4H10S) is arepresentative example, can be deodorized by reaction withhousehold bleach (NaOCl) according to the followingequation: 2C4H10S + NaOCl(aq)...........>> C8H18S2+ NaCl(aq) + H2O(aq) (1) How many grams of butanethiol can be deodorized byreaction with 5.00 ml of9.95×102 M NaOCl ?

Explanation / Answer
2C4H10S + NaOCl(aq)...........>> C8H18S2+ NaCl(aq) + H2O(aq) Molar massof butanethiol (C4H10S)is = 4 * 12 + 10 * 1 + 32 = 90 g No. of moles of NaOCl is = Molarity * Volume in L = 9.95 * 10^-2 M * 5 * 10^-3 L = 4.975 * 10^-4 moles 2 * 90 gof butanethiol (C4H10S) requires 1 mole of NaOCl X g of butanethiol (C4H10S) requires 4.975 * 10^-4 moles of NaOCl X = ( 2 * 90 * 4.975 * 10^-4 ) / 1 = 0.08955 g
