Answer:
Consider a mixture of sand and BaCl2- 2H20. A beaker containing the mixture weighed 72.248 g. When empty, the beaker weighed 69.748 g. The mixture contained 45.26% sand. % hydrate = mass of the hydrate = (a) What is the % hydrate and mass of the hydrate in the mixture? moles water lost = grams water lost = (b) If the mixture was selectively decomposed by heating, how many grams and moles of water would be lost?
