A red rubber dodge ball sits in a 20.0ºC basement, filled with 3.50L of compressed air. Eager to begin practice for the impending dodge ball season, Vince reclaims the ball and takes it outside. After a few hours of practice, the well sealed ball has a volume of 3.00L. What’s the temperature outside in Celsius?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

What term describes technology that operates on an atomic level

Iwould appreciate if someone could me.
