A) 495 g

B) 480 g

C) 525 g

The products formed are

1992019533_tttt.JPG

So , 1.5 mol of 

                 1992019503_dddd.JPG are produced from

10 moles of acetophenone.

      Molar mass of       

199201981_molare.JPG = 240+14+4+72=330

      Hence , amount of 

                                1992019519_molar.JPG   produced  is 330x1.5  =495 g
