If 15.60g of a hydrated compound is heated in an oven for several hours, its mass drops to 8.63g. assuming that the reduction in mass is due to the loss of water what is the percentage of water in the original hydrate?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

ill try to . no promises tho.
