moles dibenzalacetone required = 15g / 234.29 g/mole = 0.06402321908 mole
1 mole dibenzalacetone is formed by 2 mole benzaldehyde, so
moles benzaldehyde required = 2 x 0.06402321908 = 0.12804643817 mole
mass of benzaldehyde required = 0.12804643817 mole x 106.12 g/mole = 13.5882880191 g
Answer: 13.588 grams
