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 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.
Why does not an atom of an element represent the actual mass of its atom?
An atom of an element does not represent the actual mass of its atom because the atomic mass listed on the periodic table is an average mass calculated based on the relative abundance of different isotopes of the element. Isotopes are atoms of the same element with differing numbers of neutrons, so the actual mass of an atom of a specific isotope may vary slightly from the average atomic mass.
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 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.
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.
