The atomic mass of hafnium is 178.49 g/mol, which means that one mole of hafnium contains 6.022 x 10^23 atoms.
To calculate the mass of 2.94 x 10^17 atoms of hafnium, we can use the following formula:
mass = (number of atoms/molecular or atomic mass) x molar mass
mass = (2.94 x 10^17/6.022 x 10^23) x 178.49 g/mol
mass = 2.94 x 10^17/6.022 x 10^23 x 178.49 g
mass = 3.48 x 10^-6 g
Therefore, the mass of 2.94 x 10^17 atoms of hafnium is approximately 3.48 x 10^-6 g.
Calculate the mass of 2.94*10^ 17 atoms of hafnium.
