Epsom salts, a strong laxative used in veterinary medicine, is a hydrate, which means that a certain number of water molecules are included in the solid structure. The formula for Epsom salts can be written as MgSO4 · x H2O, where x indicates the number of moles of H2O per mole of MgSO4. When 5.469 g of this hydrate is heated to 250°C, all the water of hydration is lost, leaving 2.671 g of MgSO4. What is the value of x? Use the longest values so (ie, 18.015 for water) etc

Thank you for the opportunity to help you with your question!

5.469 - 2.671=2.798g

water=18.015g

=18.015/2.796

=6.44

x=6.44
