To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that compound. The molar mass of elements tells you the molar mass of a compound, so you can figure this out. Molar Mass Definition The molar mass definition is the grams of a ...
This calculation means that you need one mole of salt. Now, you need to use the molar mass of salt in order to calculate how much you need to weigh out. 1mol(58.44g1mol)=58.44g This calculation means that if you wanted to make a 1 liter solution of 1M NaCl, you would need to w...
For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...
