mass of evaporating dish +hydrate 24.64
mass of evaporating dish +anhydrous salt 23.85
1.determine the mass of the water lost
2.determine the number of moles of the water lost

  • chemistry -

    24.64g = dish + hydrate
    22.34g = dish
    2.30g = mass hydrate

    24.64g = dish + hydrate
    23.85g = dish + anhydrous
    0.79g = mass H2O lost

    mols = grams/molar mass
