In this question, we need to pick up the compounds which has largest number of molecules.
00:13
First option is 1 gram of dihydrogen, that is 1 gram of h2.
00:19
To convert the mass in grams, we need to divide the mass by the molecular weight of the particular compound.
00:26
So it is 1 gram divided by it is 2 .016 gram per mole.
00:33
And the answer is, so the number of molecules of dihydrogen is 2 .9.
00:39
75 into 10 to the power 23.
00:42
Similarly it is done for the three cases as well.
00:47
Now let us calculate for 10 gram of calcium carbonate.
00:52
First it is converted to moles by dividing it with the molecular weight of calcium carbonate.
00:57
It is 0 .099.
01:01
It should be multiplied with 6 .023 into 10 to the power 23...
