Multiply the # of grams by the element's atomic weight. Or if dealing with milliliters, multiply the volume by solutions molarity.

When calculating a molecule's # of moles, multiply the # of grams by the molecular weight.

How is the number of moles of an element determined from the known mass?

To determine the number of moles of an element from its known mass, you can use the formula: moles = mass / molar mass. First, find the molar mass of the element from the periodic table. Then, divide the given mass of the element by its molar mass to find the number of moles.


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 can one determine the empirical formula from mass data?
