First look at the Right side of your equation. The steam cools from 120 to 100, not to 0. Then that 100 g of condensed steam cools to 0 C with a specific heat of 1.00. The 540*100 term is OK.
On the Left side, the entire 1100 g of ice heats up from -50 to 0C with a specific heat of 0.50, and then a mass M melts with a latent heat of fusion of 80. The left side is OK. Solve for M.
All this assumes that you are left with icewater. If m turns out negative, or greater than 1100g, all of the ice may have melted, or remained below 0 C. In that case, you will have to rewrite the equation for that possibility.
