please help me solve all 3! Thank you in advance
A 15.67 g of a hydrate of magnesium carbonate was carefully heated to drive off the waters of hydration. The mass was reduced to 7.58 g after the water was driven off. What is the molecular formula of this hydrate? Complete the molecular formula by choosing the appropriate coefficient below: MgCoz v H20 Checl OVO AWN Next page Silver nitrate has the molecular formula AgNO3. In a 216.8 g sample...

CHM 010 On-Line Lab, Formula of a Hydrate PURPOSE: To determine the formula of Cuso..x H20. In other words, to determine the value of "X". PROCEDURE: When copper(II) sulfate x hydrate, a blue crystalline solid containing embedded water molecules (called a hydrate), is heated in air, it loses the water molecules and the blue solid is transformed to a white anhydrous (no water) crystal known as anhydrous copper(II) sulfate. The "x" represents a whole number of water molecules attached to...
