Hello, my name is john, and for this question, we have to find the number of moles of the indicated substances present in each of the following samples.
00:08
So let's start off.
00:12
For every one mole of li2 -co3, it weighs approximately 73 .891 grams.
00:23
So the amount of moles comes out to be 2 .64 times 10 to the negative 5th.
00:35
Moles of li2 co3.
00:39
For b, we have to convert it to grams.
00:49
For every one mole of c -a -c -l -2, it weighs 110 .98 grams.
00:59
And the amount of moles comes out to be 38 .11.
01:06
Moles of c -a -c -l -2.
01:09
Next one, we have to convert it to grams once again.
01:12
For every one mole of srcl2, it weighs approximately 158 .53 grams...
