When heating sodium carbonate decahydrate (Na2CO3·10H2O), it loses water molecules as it converts to anhydrous sodium carbonate (Na2CO3). The molecular weight of Na2CO3·10H2O is approximately 286 g/mol, while that of anhydrous Na2CO3 is about 106 g/mol. The weight lost due to the water is around 180 g/mol (from 10 moles of water), leading to a percent loss in weight of approximately 62.9%.

When cuso45h2o is heated in a crucible there is a loss of water how is the amount of water loss determined?
The amount of water loss from cuso4·5h2o can be determined by measuring the weight of the crucible and compound before and after heating. The initial weight represents the compound with water, and the final weight after heating will show the loss of water as the difference in weight. By subtracting the initial weight from the final weight, the amount of water lost can be calculated.
How to calculate percent weight loss accurately?
