So for this problem, we want to find if one gram of hydrogen molecules contains as many hydrogen atoms as one gram of hydrogen atoms themselves.
00:16
So let's first calculate how many hydrogen atoms will be in one gram of hydrogen molecules.
00:22
So you have one gram of h2.
00:26
And the only thing that we need to do is we need to just multiply or divide by the molar mass of h2 so we get moles of h2.
00:34
So we know that in one mole of h2, that the molecular mass of h2 is 2 .016mu, in this case, 2 .016 grams.
00:46
Now, all we need to do is convert moles of h2 into moles of h.
00:53
And so we know that for every mole of h2, we have two moles of h because two hydrogen atoms are in every single molecule of h2.
01:04
And finally to go from moles of h to atoms of h, we just multiply by alba goddra's number...
