How do you convert the mass of a substance to the number of moles in a substance?
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar...
