We are asked to find the mass of grams of a single element of the following elements.
00:10
First we have antimony, which is, why can't i find antimony? there it is.
00:19
It has a molar mass of 121 .76 grams per mole, and palladium is 106 .42.
00:32
First we'll do antimony.
00:37
And for this, i'm going to take one atom, which i'm considering an exact number, times 6 .022 times 10 to the 23rd atoms per mole times 121 .76 grams per atom.
01:02
Let me do this quickly and this will equal 2 .029 times 10 to the minus 22 second grams for an antimony atom.
01:33
Second, let's do palladium, same, oops, same calculation, just a different molar mass...
