You Answered Correct Answer A sample of neon gas (Ne: monatomic, molar mass M = 20.2 g/mol) at a temperature of 6.86°C is put into a steel container of mass 69.0g that's at a temperature of -51.4°C . The final temperature is -16.3°C. (No heat is exchanged with the surroundings, and you can neglect any change in the volume of the container.) What is the mass of the sample of neon (in grams)? Specific heat of steel 502.4J/kgK Ideal Gas constant R-8.31446J/(K-mol) 64.42 85.0929 margin of error +/- 1%
