Question

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 ? The odor of skunks is caused by chemical compounds calledthiols.

(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
