Explanation / Answer

1. Correction factor is +2 0C

Volume of a rectangular plate is length*breadth*height [Where * stands for multiplication]

therefore volume =28.37cm3

Density =mass/volume= 0.549 g/cc

mass of hydrated compound is the extra mass in hydrated + crucible compound

which is 78.1-75.4=2.7g

after final heating,the compound becomes anhydrous,therefore the mass of it is 77.1g

,mass of water in hydrated compound is 1g (78.1-77.1)

% of water is = (mass of water/mass of hydrated compound)*100
