Question

an element x exist as x4 in benzene

Answer 1

Answer:

An element X of atomic mass 25 g exists as X, in benzene to the extent of 100%. When 10.30 g of saturated solution of X in benzene is added to 20.0 g of benzene, the depression in freezing point of the resulting solution is 0.51 K, If K of benzene is 5.1 K kg mol-1, the solubility of X in 100 g of benzene will be. A) 2.9 g B)3.0 g h C) 0.7 g D) 0.3 g
