To determine the subscript of an element in a molecular formula the empirical mass must be multiplied by the actual mass?
The actual mass must be divided by the empirical mass. This was derived from the following equation: (subscript)(empirical formula) = (molecular formula) subscript = (molecular formula)/(empirical formula)
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 do you determine the molar mass of an element?
U have to divide the mass lol
Why does not an atom of an element represent the actual mass of its atom?
The atomic mass of an element is measured not in the mass of the atom, but in the number of grams per mole.
How do you determine the mass of an element?
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.
Why does not atomic mass of element represent the actual mass of the atoms?
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
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 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.
To determine the molar mass of an element one must know the elements what?
penis
What instrument can be used to determine the identity of an element if its flame color is the same of another element?
Mass spectrometer would work.
