Benzoic acid, c6h5co2h, dissolves in concentrated sulfuric acid to give a cation with the formula c6h5co2h+2 , where an oxygen atom has been protonated. there are two possible oxygen atoms for protonation in this molecule, but the experimental evidence suggests that only one protonated species is formed in measurable amounts. what is the structure of the ion formed, and why is it the only major product of the reaction?

What volume will 12g of iron occupy?SolutionIron is a solid substance at room temperature. You can find the volume of solids (and of not solids) using the density.
You can obtaindthe density of most pure substances in the internet. The density of iron at room temperature is 7.874 g/cm³.
Thus, substituting in the formula, you get:
The answer is rounded to two significant figures because the input, 12g, has two significant figures.
