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.

What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
In addition to the percent by mass of each element, you also need the molar mass of each element. This information allows you to convert the percent by mass into grams and then into moles, which is necessary to determine the empirical formula and subsequently the molecular formula of the compound.
What are the steps for calculating molar mass of compound?
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
How can one determine the empirical formula from mass percent composition?
To determine the empirical formula from mass percent composition, one must convert the mass percentages of each element in a compound into moles. Then, divide the moles of each element by the smallest number of moles to find the simplest whole number ratio of elements in the compound, which represents the empirical formula.
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 one determine the empirical formula of a compound?
To determine the empirical formula of a compound, one must find the simplest whole number ratio of the elements present in the compound. This can be done by analyzing the mass percentages of each element in the compound and converting them to moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. This ratio represents the empirical formula of the compound.

What does one determine a percent composition from an empirical formula?
To determine the percent composition from an empirical formula, first calculate the molar mass of the compound by summing the atomic masses of all the elements in the formula. Then, for each element, divide its total mass in the formula by the compound's molar mass and multiply by 100 to get the percentage. This process provides the proportion of each element in the compound relative to the total mass.

How can one determine the oxidation number of an element in a chemical compound?
To determine the oxidation number of an element in a chemical compound, you need to follow these steps: Identify the element in the compound. Determine the common oxidation states for that element. Assign the oxidation number based on the compound's overall charge and known rules for assigning oxidation numbers. By following these steps, you can accurately determine the oxidation number of an element in a chemical compound.
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.
How can one determine the empirical formula from percentages of elements in a compound?
To determine the empirical formula from percentages of elements in a compound, first convert the percentages to grams. Then, divide the grams of each element by its molar mass to find the moles of each element. Next, divide the moles of each element by the smallest number of moles to get the simplest whole number ratio. This ratio represents the empirical formula of the compound.
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.
Which is usually the larger number the mass number of an element or the formula mass of a compound that contains the element?
The formula mass of a compound that contains the element would be a larger number than the mass number of the individual element. The individual element would simply be the mass of just that one atom, where as the compound would be the mass of that atom plus the other masses of the other atoms that make up the compound. ex. Oxygen-O has a mass number of about 16 grams. Water-H2O has a formula mass of 2 x mass of Hydrogen-H (about 1) + the mass of Oxygen-O 16 = 18 grams. A formula mass of 18 g is more than a mass number of 16 g.
