For 2Na (s) + Cl2 (g) - 2NaCl (s) how many grams of sodium chloride will be made from 115 g of sodium metal when when reacted with excess chlorine gas. Write the symbol for every chemical element that has atomic number less than 14 and atomic mass greater than 23.3 u. Molar mass: Mass of the one mole of the substance is called molar mass it is numerically equal in gram(g) to the atomic mass in unified mass (u) Molar mass of the Cl2 molecule = (35.5×2) = 71g/mol. Mass = number of moles × molar mass. 7.1g = number of moles × 71g/mol. 7.1/71mol = number of moles. 0.1mol= number of moles.
Molar mass of Cl2 = 70.906 g/mol
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. The total mass of the products is 50g. Which best completes the other two amounts? The amount of CD is 40 g, and the amount of AC is 35 g. The amount of CD is 35 g, and the amount of AC is 40 g. The amount of CD and AC would be the same. The amount of CD and AC is undetermined.

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.
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.
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.
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.
The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. 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.
Finding molar mass starts with units of grams per mole (g/mol). Bfme2 rise of the witch king patch 2.01 crack. 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.
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.
