T = 3.45 x 102 K
Vi = 230 m/sec
Vf = 231 m/sec
V = ( Vi + Vf ) / 2
= ( 230 + 231 ) / 2
V = 230.5 m/sec

Name Lab Section _Date The Mole Concept and Atomic Weights The purpose of this activity is to better understand the concepts of relative atomic mass, counting by weighing and the mole. Percent composition and average atomic mass are included. Part I. Relative Atomic Masses and the Mole - Early Method When John Dalton proposed his atomic theory, he stated that the atoms of each element...
