using using using Moles and Chemical Formulas-CHM100 Lab 7 The simplest formula of the magnesium oxide product is determined by calculating the moles of wnesium and the moles of oxygen using their respective atomic masses. eet- Moles and Chemical Formulas-CHM100 Lab 7 Don't forget units in your data and calculations B19 Moles of water removed (Show calculations) . 158 moves B20 Moles of anhydrous salt (Use the correct molar mass for the salt you chose) 15g, 6 B21 Ratio of moles of water to moles of anhydrate , l 58 1a - |-moles water moles of anhydrate 1 mole anhydrate moles of water o.ol3 B22 Write the correct formula for your starting hydrate using your calculations in B21 blems and Queries Using the formula from B22 for your hydrate, write a balanced equation for the dehydration reaction you performed. . Using the rules for writing the formulas of ionic compounds, write the ions and the correc of magnesium oxide.Explanation / Answer
From the given data,
moles of water/moles of anhydrous salt = 12
B22. Correct formula for the starting hydrate = MgO.12H2O
1. balanced equation for the drhydration reaction,
MgO.12H2O --> MgO + 12H2O
2. ions = Mg2+ and O^2-
correct formula = MgO
