How many grams of Li2O must be carried on board to remove 85.0kg of water?

  • chemistry -

    Li2O + HOH ==> 2LiOH
    mols H2O = 85,000/18 = estimated 4722
    Now convert mols H2O to mols Li2O using the coefficients in the balanced equation. That's estimated 4722 x (1 mol Li2O/1 mol H2O) = about 4722 mols Li2O.
    Now convert that to g Li2O. g = mols x molar mass.
    Go back and confirm my estimates.
