0.06105 moles is the number of moles of water lost.
<h3>What is molar mass?</h3>Molar mass is defined as the mass in grams of one mole of a substance.
Given data:
Mass of water = 1.1g
Molar mass water = 18.016 g/mol
Moles of water =?
These quantities are related by the following equation;
Moles =
Substituting the values of the quantities and solving for moles, we have;
Moles = = 0.06105 moles.
Hence, the 0.06105 moles is the number of moles of water lost.

Answer:
Explanation:
Hello,
In this case, for such formation of sulfur hexafluoride, the standard enthalpy of formation is -1220.47 kJ/mol (data extracted from NIST database). Next, we compute the moles in 10.0 grams of sulfur hexafluoride as shown below:
Next, for the given energy, we compute the total heat that is liberated:
Finally, we conclude such symbol has sense since negative heat is related with liberated heat.
Best regards.
