A scientist has 4 pieces of copper. Each piece is a different shape and size (samples A through D). The scientist measures the volume and the mass of one sample, but measures only the volume or only the mass of the other samples. Since the scientist knows that copper is a substance, the scientist claims that she can predict what the mass will be of sample B and C. She also claims she can predict what the volume will be of sample D. Using the information in the table below, find the volume of sample D.

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
