![Pb(C_2H_5O_2)_2.3H_2O[tex] Name = lead(II) hydrate trihydrateExplanation:Mass of the hydrated salt = 8.00 gMass of water lost = 1.14 gMass of the dehydrated salt = 8.00 - 1.14 g = 6.86 g The moles of the dehydrated salt is : Amount = 6.86 g Molar mass of [tex]Pb(C_2H_5O_2)_2[tex] = 329.3198 g/molThe formula for the calculation of moles is shown below: [tex]moles = \frac{Mass\ taken}{Molar\ mass}](/tpl/images/0329/9305/3cb78.png)
![H_2O[tex] = 18 g/mol The formula for the calculation of moles is shown below: [tex]moles = \frac{Mass\ taken}{Molar\ mass}](/tpl/images/0329/9305/5f114.png)
