WebLithium for instance has an atomic mass of 6.941 grams and this is equal to one mole of lithium. This is why we state the atomic and molecular masses in units of grams per mole or g/mol. What can we do with moles? We use the unit to make calculations based on balanced chemical equations. WebSo what I did was start with my given molarity as mol/L. I assumed there wouldn't be enough solute to drastically affect density and so I changed 1 L to 1000g, so I ... For example, if you have 50 g of water and 50 g of salt, then the solvent would be the water, as you put the salt IN the water, not the water IN the salt. Comment Button ...
