Calculate the number of grams of ice at 32 celsius that can be melted by 1g of 100 degrees celsius steam

(g steam x heat vap) + (mass ice x heat fusion) + [(mass steam H2O x specific heat x (Tfinal-Tinitial)] + [mass melted ice x specific heat x (Tfinal-Tinitial)]= 0

I don't know what units you ae using; you substitute them.
(1g x -heat vap) + (xgrams x heat fusion) + [(1g x specific heat H2O x (32-100)] + [(xgrams x specific heat x (32-0)] = 0
and solve for x grams.
Check my thinking.
