Unknown/Mole Lab
Mole Lab!
Tenchita, Timmy, Serena and I had a lot of fun in this lab just because we felt like really scientists. We were told to figure out the atomic mass given only the number of moles. We weighed each cup to find out the grams and then took the number of grams divided by the number of moles to get the atomic mass. Given the atomic mass we find out what the element was.
Avogrado's number - (6.0221367 x 10^23).
Data
Sample. Number of moles. Grams. Atomic mass. Element
A. .163 6.53 40.061 Ca
B. .910 24.51 26.934 Al
C. .160 9.44 59 CO
D. .258 53.90 208.9 Bi
E. .220 14.26 64.81 Zn
F. .756 49.26 65.158 Zn
G. .492 28.66 58.25 Ni
H. .430 89.16 207.349 Pb
I. .381 21.28 55.85 Fe
J. .259 30.70 118.53 Sn
