The moles of vapor released is 0.357 mol/H2O
The molar mass of the salt is the same as that of water times the moles of H2O
<h3>mgso4·7h2o</h3>
This is also the same as:
Molar mass of (MgSO₄) + 7 * molar mass of (H₂O)
Molar mass of (MgSO₄) = 168g/mol
molar mass of (H₂O) = 18 g/mol
mgso4·7h2o = 168 +7*18
= 168+126
= 294g/mol
<h3>15.5 mols of mgso4·7h2o</h3>
= 0.357
The moles of vapor released is 0.357 mol/H2O
