I got to get to zero. So you say I need to make things more negative Sulfate comes as -2 so I can add another negative too. I got to become more positive So I can add another. Iron is plus three. Three plus three is six minus two is four minus two. Is to we're still not there but we need to become more negative, we can add another sulfate and now three plus three is six negative two negative two, negative two is negative six.
And now we have something with a neutral charge. So how many irons did I use I use to? How many sulfates did I use? I used three. So let's come back to the formula on the left.
That too became the value here. Now S. And when we want to show groups, just like in algebra, when you want to show groups, you use a parentheses to show groups. And how many groups do we have? So that's why we have a neutral compound for iron three sulfate When we take to iron ions and three sulfate ions and put them together. An aqueous solution of iron II sulfate is paramagnetic. The ionic compound AB is formed. Explain why ions with charges greater than 3 are seldom found in ionic compo… Problem Which of the following atoms would be expected to….

This is how to calculate molar mass average molecular weight , which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes.
For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.
The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom or group of atoms in the formula by the formula weight and multiplying by
