to convert an element to moles you need to setup and equation, for our example we will be using 5g of O2 or oxygen. You need to know what O2's molar mass is as well, it is 32g.
So the equation would be 5g of O2 / 32 = .16 moles of O2. So to convert moles to grams all you do is multiply the moles given by the molar mass of the element/compound and you have your grams
Hoped this helped : )

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 is the number of moles of en element determined from known mass?
The number of moles of an element can be determined using the formula: moles = mass (grams) / molar mass (grams per mole). First, you need to find the molar mass of the element from the periodic table. Then, divide the known mass of the element by its molar mass to calculate the number of moles. This allows you to convert the mass into an amount expressed in moles.
How does one determine an empirical formula a percent composition(apex)?
To determine the empirical formula from percent composition, first convert the percentage of each element into grams (assuming 100 grams of the compound). Next, convert the mass of each element to moles by dividing by its atomic mass. Then, find the simplest whole-number ratio of the moles of each element by dividing by the smallest number of moles calculated. This ratio gives you the subscripts for the empirical formula.
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
A substance contains 5.00 g C and 1.70 g H What is the empirical formula?
Well, darling, to find the empirical formula, you need to convert the grams of each element to moles. Then, you divide the moles of each element by the smallest number of moles calculated. In this case, the empirical formula would be CH3. Happy calculating, sugar!

How is the number of moles of an element determined froma known mass?
To determine the number of moles of an element from a known mass, you use the element's molar mass (grams per mole). Simply divide the given mass of the element by its molar mass to calculate the number of moles. This relationship is described by the formula: moles = mass (g) / molar mass (g/mol).
How does one determine an empirical formula a percent composition(apex)?

How can one determine the chemical formula from percent composition?
To determine the chemical formula from percent composition, you need to convert the percent composition of each element into moles. Then, divide the moles of each element by the smallest number of moles to find the ratio of elements. Finally, use this ratio to write the chemical formula.
How to calculate the empirical formula from mass percentages?
To calculate the empirical formula from mass percentages, first convert the mass percentages to grams. Then divide the grams 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, which represents the empirical formula.
