The hydrated salt Na2CO3.xH2O undergoes 46% loss in mass on heating and becomes anhydrous.then wat is the value of 'X'?
The hydrated sodium carbonate is converted into anhydrous sodium carbonate on heating which means that X molecoles of water are separated completely. Therefore the loss in weight is equal to the X molecules of water.
46% of the weight of hydrated sodium carbonate=18X molecules of water
the molecular weight of sodium carbonate is 106 and that of water is 18
therefore 46%*(106+18X)=18X
find the value of X
