You have been given a sample of the unique Macro You have been given a sample of the unique Macro Element Beanium. Each sample of beanium contains Element Beanium. Each sample of beanium contains the same amount of each beanium isotope, B. beanium the same amount of each beanium isotope, B. beanium and W. beanium. The average mass of Beanium is and W. beanium. The average mass of Beanium is based on a weighted average that is determined by the based on a weighted average that is determined by the isotope’s abundance in nature. Calculating the average isotope’s abundance in nature. Calculating the average atomic mass of beanium is just like calculating your atomic mass of beanium is just like calculating your average in chemistry class. Use the abundance in average in chemistry class. Use the abundance in nature and the average mass of each isotope to nature and the average mass of each isotope to determine the average atomic mass of beanium.determine the average atomic mass of beanium.

On February 11 at Salado, south of Saltillo, they attempted a mass escape. After nearly starving in the arid mountains, 176 of the 193 escapees were recaptured and returned to Salado, Tamaulipas, Mexico. (However, three escapees did reach Texas.) Soon after they arrived at the Salado on March 25, 1843, they were informed that they were to be decimated (every tenth man shot) by order of Mexican dictator Antonio López de Santa Anna.

Seventeen black beans and 159 white beans were placed in a vessel and each man was required to draw out one. Those drawing black beans were swiftly shot. Ewen Cameron, who had engineered the escape, drew a white bean but was executed afterwards by special order bringing the total executed to 18. The bodies from the failed Mier Expedition were returned to Texas and are buried on Monument Hill at La Grange, Fayette County.
