# Waters of crystallisation HELP! watch

1. Hey guys,

Would someone kindly give me a step-by-step guide on how to solve this problem?

{Hydrated sodium carbonate (Na2CO3•6H2O) has a molar mass of 214g/mol. When 4.82g of this salt is heated, the salt loses water in its molelcule and forms 3.198g of solid product. Use the information to determine the formula of this solid product}

I don't have any problems with other questions but just confused by how I work this one out.

Any help much appreciated.

Thanks
2. First, you need to work out how many moles of sodium carbonate there is in 4,82g. You have to make your own input.

That isn't helpful to OP, he is clearly struggling.
