an Mr, of 246. The crystals were heated on low flame, and it was found that 1.02g
water was present in the sample. Calculate the total mass of water present in the
hydrated crystal mentioned above, and determine the value of x.​

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
