Molar mass is calculated as a total of the atomic masses of all atoms that are present in a given compound. The atomic masses can be found in the periodic table. What is the formula to find molar mass? The molar
The atomic mass of aluminium is given to be 27 u. This means that 1 mole of aluminium atoms has a mass of 27 grams. Now, 1 mole of aluminium atoms = 27 g So, 4 moles of aluminium atoms = 27 xx 4 g = 108 g Thus, the mass of 4 mole
