Consider the reaction.
A 3.67-L flask containing an equilibrium reaction mixture has [H2] = 0.104 M and [I2] = 0.0202 M. What mass of HI in grams is in the equilibrium mixture?
Chapter 3: Composition of Substances and Solutions Molecular and Formula Mass The molecular mass is the mass in atomic mass units (amu) of an individual molecule. o To calculate the molecular mass, multiply the atomic mass for each element in a molecule by the number of atoms of that element and then total the masses. Example: Molecular Mass of HOH= 2(atomic mass of H) +atomic mass of O =2(1.008)+16.00amu=18.02 amu Molecular weight is an average molecular mass, determined by the periodic table atomic masses, which are average atomic masses. Formula Mass Formula Mass- a sum of the atomic weights of the
