Q. ___grams of 3-Hydroxy propanal $(M W = 74)$
must be dehydrated to produce $7.8 g$ of acrolein $(M W = 56) (C_{3} H_{4} O)$ if the percentage yield is
64. (Round off to the Nearest Integer).
[Given : Atomic masses $: C : 12.0 u, H : 1.0 u, O : 16.0 u$ ]

$\frac{x}{74}$ mol

$\frac{x}{74} \times 0.64 = \frac{7.8}{56}$

$x = 16.10$

$≃ 16.00$
