a 3.00 g mas of coumpound X was added to 50.0 g of water and it is found that the freezing point has decreased by 1.25 C what is the molar mass of X if it has a van't Hoff factor of 3

What reaction is taking place? 02 + c3h8 = h20 + co2

The tilt of the earth's axis of rotation is responsible for the a) ocean's tides. b) size of the moon. c) brightness of stars. d) earth’s seasons.
