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...
