The mole concept, which we will introduce here, bridges that gap by relating the mass of a single atom or molecule in amu to the mass of a collection of a large number of such molecules in grams. For example, in the methane molecule one carbon is connected to four hydrogen atoms simultaneously, while each hydrogen atom is connected to only one carbon. In 1 mole of Hydrogen gas, there are 12.0410^23 atoms. There are 88 Since each sulfuric acid molecule contains 4 oxygen atoms, there are about 20 moles of sulfuric acid molecules. blockquote.testimonial p, I highly recommend Norm\'s classes to those who are committed to earning higher sales numbers.
