SUMMARY
To calculate the total mass in kilograms from atomic mass units (amu), multiply the number of atoms by the atomic mass in amu and then convert to kilograms using the conversion factor 1 amu = 1.66053904 x 10-27 kg. For a helium atom with a mass of 4.0 amu and 6.0 x 1024 atoms, the total mass is calculated as follows: Total Mass (kg) = 6.0 x 1024 atoms * 4.0 amu * 1.66053904 x 10-27 kg/amu, resulting in a total mass of approximately 3.984 kg.
