Question

Black Forest Biologicals, a biotech startup, has a promising Alzheimer's drug candidate Compound SLT-88 entering Phase I trials this year. SLT-88 is the only product formed by the reaction of two precursor compounds A and B, both of which are quite expensive. The chief medicinal chemist of Black Forest is trying out different reaction conditions to minimize the cost of manufacturing SLT-88. In the table below are listed the initial and final amounts of A and B used under two different trial conditions, and also the actual amount of SLT-88 recovered in each case. Complete the table by calculating the theoretical yield of SLT-88 and the percent yield of SLT-88. Round your amounts to the nearest milligram and your percentages to the nearest whole percent. all amount of A amount of B yield of SLT-88 09 Hº Trial initial final initial final theoretical actual 0.0 1000 mg 0 mg 350. mg 231. mg 817. mg 0 mg 250 mg 150 mg 40 mg

Answer 1

A+B - Product (SLT-8) Man can not be destroyed or created. So, for this reaction Man of AfB reacted & man of product. here, since in both trial Fimoint of A is ong but final amount of ab is not ong So, here, & is limiting reactant 4 is excess reactant for trial. 1 man of À reacted = 1000mg man of s' u u (950 - 231.0) ng - 119.0 mg " According to earration (1) man of Eroduct formation theoritically (119 +1800) ing= 1119 ing % of yield & Actual yield Treoriticar yield100% . 817. 0mg x 180%. 19 ing – 73.01% Similarly for trialz - theoriticar yield of product = 2550 + (250-150)} mg - 650mg .: % of yielde spo x100'). - 86.0%
