We have given molecular formula here and we will calculate the molecular mass.
00:05
So we have c6h6o.
00:09
So this will be 6 multiplied by atomic mass of carbon plus 6 multiplied by atomic mass of hydrogen plus atomic mass of oxygen.
00:18
So that is 6 multiplied by 12 plus 6 multiplied by 1 plus 16.
00:26
So that will be equal to 94 atomic mass unit.
00:36
Similarly for b part, we have h2so4.
00:44
So that is 2 multiplied by atomic mass of hydrogen plus atomic mass of sulfur plus 4 multiplied by atomic mass of oxygen.
00:54
So that is 2 multiplied by 1 plus sulfur, atomic mass of oxygen.
00:59
Mass is 32 plus 4 multiplied by oxygen atomic mass is 16.
01:06
So this will be 98 atomic mass unit.
01:11
Now see part c6 h6.
01:18
So this will be 6 multiplied by atomic mass of carbon plus 6 multiplied by atomic mass of hydrogen.
01:26
So that is 6 multiplied by 12 plus 6 multiplied by 1.
01:32
So that will be 17, 78, sorry, 78 atomic mass unit...
