Describe two independent methods for determining the atomic mass of an element. Explain how these method are truly independent.
calculate the concentration in mol/L and mg/L of a solution prepared by adding 4.00 mL of a 8.26 x 10^-4M stock solution of Allura Red to a 100.00 mL volumetric flask and then filling to the mark with DI water.
Kinetic Molecular Theory states that particle collisions are elastic,but energy and collisions of the particles are proportional to the absolute temperature, but the more collisions according to Henry's law, the more gas dissolves.
