What mass of steam initially at 130◦C is needed to warm 200 g of water in a 100-g

What mass of steam initially at 130◦C is needed to warm 200 g of water in a 100-g glass container from 20.0◦C to 50.0◦C at thermal equilibrium? (Specific heats of water,steam and glass are 4.19 × [tex]10^{3}[/tex], 2.01 × [tex]10^{3}[/tex] and 837 J/kg ·◦C, respectively. The latent of vaporization of water is 2.26 × [tex]10^{6}[/tex] J/kg.)
