Let's solve the question.
00:02
First, we calculate the number of moles of pin.
00:07
So, that will be equal to mass which is 98 grams divided by the atomic mass which is 118 .7 grams per mole.
00:20
So, that will be equal to 0 .825 mole.
00:26
Now, number of moles of lead.
00:33
So, that will be equal to mass which is 65 grams divided by the atomic mass which is 207 .2 grams per mole.
00:43
So, we get the answer which is 0 .313 mole.
00:49
Now, next we calculate the total number of moles.
00:53
So, the total moles will be equal to 0 .825 mole plus 0 .313 mole...
