Answer» <p>both the compound zn and Ca have valency 2, so theit molecular formula will be X2Y2 </p> <p>wrong ans.</p> <p>what is the answer then??</p> <p>x2y3</p> <p>Given the compounds have equal mass of them in a formulasuppose the mass is M so , no. of moles for X = M/30and for Y = M/20</p><p>so x/y = 2/3 </p><p> from above the molecular formula will be X2Y3</p>
