no, we have We have given the information that there are there is 100 gram off sulfur so we need to find number of most off sulfur because we need to know how many atoms off cell for there are. Find that we need to know most first, because that way we can multiply by abogados number on we can get the number of atoms so number off most is given by 100 divided by 100 is the next mass available to us divided by 32.1? That's the atomic mass off sulfur. So this gives you the answers. 3.1 two. So they're these many number of most are available to us. So number of atoms in this case is equal to number of molds. That is 3.12 times a bug address number that's 6.23 times 10 power 23. This gives you 18 point eight times 10 power 23. No, The next part reads that you put an extra electron on one in 10 power 12 off its atoms. So we need to find how many of these atoms are there. So let's find out the net atoms atoms with extra electron. To find this out, we need to find the fraction or the Yeah, the division that is 18.8 times 10 power 23 divided by 10 Power 12 Because we have we are placing one intern power 12 off atoms with extra electrons. So we have these many number of electrons. This is so this many number of patterns Net and these many number of atoms were choosing one atom from these many number of Saturn's were children so that we have extremely trance and feel of the atoms. So let's do this calculation. We get 18.8 times 10 power 11 So these are the atoms number of atoms with extra electron. So next part is to find out the charge. To do that, we are going to multiply the number here by electronic charge. So 18 point it times 10 power 11 times Elektronik charges 1.6 times 10 power Negative. 19. So that will be 30 10 times 10 power. Negative eight. Cool. Oh, if you want to write in term self micro courtroom, you can write us point zero. Sorry. 0.3 micro cooler. So That's the charge neck charge you'll be placing if you decide to put one intern power 12 atom with one extra electron.
