Final answer:
To determine the mass of an atom, you need to know the atomic mass of the element. You can find this information on the periodic table. Calculate the mass of an atom by multiplying the number of each type of atom in the formula by the atomic mass for each element and then add up the masses for all the elements.
Step-by-step explanation:
To determine the mass of an atom, you need to know the atomic mass of the element. You can find this information on the periodic table. The atomic mass represents the average mass of all the isotopes of an element, taking into account their abundance. To calculate the mass of an atom, you multiply the number of each type of atom in the formula by the atomic mass for each element and then add up the masses for all the elements.
