1.	0 . 32 mole of LiAIH_(4) in ether solution was placed in a flask and 74 g (1 mole) of t- butyl alcohol was added. Theproduct LiAIHC_(12)H_(27) O_(3)weighed 81.28 g . Isthe claim that theyield is 'quantitative'a valid oneif Li atoms areconserved ? (Li = 7, Al = 27, H = 1, C = 12 , O = 16)
Answer» Solution :`{:(LiAIH_(4)""underset("alcohol")OVERSET("t - butyl")to""LiAIHC_(12)H_(27)O_(3)),("0 . 32 mole81 . 28 "g ):}` Applying POAC for Li atoms, MOLES of Liin `LiAIH_(4) `moles of Li in `LiAU=IHC_(12) H_(27) O_(3)` `1 xx ` molesof `LiAIH_(4) = 1 xx ` molesof `LiAIHC_(12) H_(27)O_(3)` Thus, 0 . 32 mole of `LiAIH_(4)`shouldproduce 0 . 32 mole of `LiAIHC_(12) H_(27) O_(3)` if theyield is QUANTITATIVE, i.e., `100%` Moles of `LiAIH_(12)H_(27) O_(3) = (81. 28)/(254)= 0 . 32`mole(Rule, 1 Chapter 1) (mol. wt. of `LiAIHC_(12) H_(27) O_(3) = 254` ) Thus the yield is `100%`
