thermodynamics steam tables?

A rigid vessel of volume 2.5 m3 contains steam at a pressure of 6 bar and a dryness fraction of 0.75. If the contents of the vessel are heated, determine: i) the pressure at which the steam becomes dry saturated, ii) the temperature of the steam when the pressure reaches 10.0 bar, iii) the heat transfer to the steam in attaining state b). Don't need full solutions just not sure where to start thanks !
