Hi sorry I was busy. From my understanding superheated steam is above its bubble point at the same pressure. By Gibbs phase rule, you have two variables you can vary independently for superheated steam. I would say you need to find two sets of data from the steam table at 1.013 bars( atmospheric pressure) 100 degree C and another date set at 1.013 bars, higher than 110 degree C.

Take saturated steam at 1.01325 bars 100 degree C, hg and hg at 1.01325 bars at 150 degree C superheated steam and interpolate them to 110 deg C, should get the answer.

Maybe your teacher answer is based on a different steam table, anyway the answer is close enough, dun have to sweat over the small difference
