After distilling your crude methyl benzoate, you set aside 5.12 grams of the purified ester. you then prepare the grignard reagent ( phenylmagnesium bromide ) by reacting 2.1 grams of magnesium with 14.12775 ml of bromobenzene. you add the 5.12 grams of methyl benzoate to the freshly prepared grignard reagent to form an addition product.
finally, after hydrolyzing the grignard addition product, you obtain 5 grams of the final product, triphenyl carbinol.
what is the percent yield of triphenyl carbinol ?
( the density of bromobenzene is 1.495 g/ml )
gas molecules will never collide with the walls of the container
as per as the multiplication rules of the significant figures, whenever any numbers in the decimals forms are multiplied or divided then result in mentioned in such a way so that the significant figures after the decimal will be same as that in the given least condition.
102900/12 = 8575
170 × 1.27 = 215.9
∴ (102,900 ÷ 12) + (170 × 1.27) = 8575 + 215.9
now, as per as above rules, answer in correct significant figures will be = 8791.
