1) Find the average atomic mass of the element, given the isotopic percentage of 75.0% for Cl-35 and 25.0% for Cl-37. 2) The part of an element that never changes is. Electric charge. Oxidation number. 3) The positively charged particle in the nucleus.
Molar mass of CuO = 79.5454 g/mol
This compound is also known as Copper(II) Oxide.
How to Convert Atomic Mass Unit to Gram. 1 u = 1.6605402E-24 g 1 g = 6.752E+23 u. Example: convert 15 u to g: 15 u = 15 × 1.6605402E-24 g = 2.4908103E-23 g. Popular Weight And Mass Unit Conversions. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Weights of atoms and isotopes are from NIST article. = 18.0 8 9 amu + 0.05 1 6 amu + 2.0 3 4 amu = 20.1796 amu. Looking at our significant digits, we see that 18.0 8 9 was precise to the hundredths place, 0.05 1 6 was precise to the thousandths place, and 2.0 3 4 was precise to the hundredths place. So the answer can only be precise out to the least precise or most uncertain place, hundredths place.

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.
Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.

The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. Declutter 2020. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
