Using the combined gas law, determine the final volume of a sample of helium gas that occupies a volume of [a] mL at a pressure of [b] mm Hg and a temperature of 300.0 K. What will the volume be at a pressure of [c] mm Hg and a temperature of 793.0 K? Report to one decimal place, units are required for this question.

A piece of metal with a mass of [a] g at 165.3oC is placed in a styrofoam cup containing [b] g of water at 21.5oC. Once the system has reached equilibrium, the final temperature of the water is [c]oC. What is the specific heat of the metal to four significant digits? The specific heat of water is 4.18 J/g-oC.

The fictional element Missouthernium (Ms) has three naturally occurring isotopes. Isotope A has a mass of 199.79 amu, Isotope B has a mass of 203.45 amu, and Isotope C has a mass of 206.72 amu. If the relative abundance of Isotope A is 42.6%, Isotope B is 35.2%, and Isotope C is 22.2%, what is the average atomic mass of Missouthernium (Ms)?
