Becuase they need special equipment and things like that that may not be available in the state i think
The formula for determination of atomic mass given the mass of isotopes and relative abundance is:
Ar = ∑(mass * abundance) / 100
Ar = (68.92558 * 60.108 + 70.92470 * 39.892) / 100
Ar = 69.72306
The atomic mass of gallium is 69.72306 amu
Lead Nitrate is highly soluble in water. 37.65g/100 mL at 20*C

Now the number of effective collision is directly proportional to the number of reactants added..
