The mass of an element is the sum of the protons and neutrons in an atom. It is usually listed right on the Periodic Table.

How can one determine the mass of an element in a compound?
To determine the mass of an element in a compound, you can use the chemical formula of the compound and the atomic mass of the element. Multiply the atomic mass of the element by the number of atoms of that element in the compound, then add up the masses of all the elements present in the compound to find the total mass.
How are mass calculations used?
Mass percentage calculations determine the percentage of an element based on mass in a compound. This can then be used to determine the percentage in a compound of each individual element.
How can one determine the density of an element?
To determine the density of an element, you would need to measure its mass and volume. The density of an element is calculated by dividing its mass by its volume. The formula for density is: Density Mass / Volume. By measuring the mass and volume of the element, you can then calculate its density.
To determine the molar mass of an element one must know the elements what?
To determine the molar mass of an element, you must know the atomic mass of the element, which is found on the periodic table and is measured in atomic mass units (amu). This value represents the average mass of all the isotopes of that element.
How do you determine the molar mass of an element?
To determine the molar mass of an element, you sum the atomic masses of all the atoms in a molecule of that element. This involves finding the atomic mass of each individual element from the periodic table and adding them together based on the chemical formula. The unit for molar mass is grams per mole (g/mol).
How is the number of moles of an element determine from a known mass?
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
How do you determine neutrons in element?
subtract the atomic number from the mass number
How can one determine the mass of an element?
The mass of an element can be determined by using a tool called a balance to measure the amount of the element present. This measurement is typically expressed in grams or kilograms.
How can one determine the empirical formula from mass data?
To determine the empirical formula from mass data, you need to find the molar mass of each element in the compound. Then, divide the given mass of each element by its molar mass to find the moles of each element. Finally, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio of elements, which represents the empirical formula.
How can carbon still be considered a single element and have different mass numbers?
Every element can have different mass numbers; these reflect the number of neutrons in the atom in addition to the protons that determine which element it is.
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
How do you determine the actual mass of an element?
you dont. if you dont know then go find out
