Nitinol, an alloy of Ni and Ti exhibits shape memory. Nitinol has the ability to undergo deformation at one temperature, then recover its original undeformed shape upon heating above its transformation temperature. The width of the transformation temperature is related to the Nitinol composition. When 1.00 g Nitinol sample reacts with dilute sulfuric acid, the volume of the gas collected at 756 mmHg and 27.0 °C is 478 mL. What is the mass composition of Ni in the sample? PH2O = 26 mmHg at 27.0 °C.Note:Both Ti and Ni react with H2SO4to produce Ti3+ and Ni2+ ions, respectively. Ti = 48; Ni = 59
