Hi, in this problem, we are given the mass of so2, that is 6 .4 gram.
00:06
We have to find out the number of oxygen atoms in the given mass out of the human options, a, b, c, and d.
00:12
So let's work on this.
00:13
First, we will find out the molar mass of so2 that can be calculated by adding the masses of individual elements present in so2, that is equal to 52 gram plus 2 times 16 gram for oxygen, and this gives the value as 64 gram per mole.

Now we will find out the number of moles of sulfur dioxide in the given mass, which can be calculated by dividing the given mass by the molar mass, that is 6 .4 gram divided by 64 gram per mole, and this on calculating gives the value as 0 .1 mole...
