Molar mass is the mass (in atomic mass units) of one mole of a of a substance. One atomic mass unit (u) is equal to 1/12 the mass of one atom of carbon-12. It is also sometimes called: Molecular Mass, Molecular Weight, Formula Mass, or Formula Weight.
Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa. Computing molecular weight (molecular mass)
The formula weight of a substance is the sum of the atomic weights of each atom in its chemical formula. For example, water (H 2 O) has a formula weight of: \[2\times(1.0079\;amu) + 1 \times (15.9994 \;amu) = 18.01528 \;amu onumber \]
New! free android application: Thermo FW Calculator. A versatile formula weight calculator that can handle fractions and decimals in formula.
Jan 18, 2024 · Our molar mass calculator comes to the rescue if you need to quickly check the weight of 1 mole of any element or chemical compound and you are unable to use the periodic table. Simply select one by one the elements from the list and give the number of atoms in their molecular formula to get the molar mass in a flash.
May 18, 2023 · The key to calculating the formula weight of an ionic compound is to correctly count each atom in the formula and multiply the atomic weights of its atoms accordingly. Example \(\PageIndex{1}\) Use the atomic masses (rounded to two decimal places) to determine the formula weight for each ionic compound.
Formula Weight Calculator. Formula: Formula weight: Enter elements in proper case, for example, H for hydrogen not h Cl for chlorine, neither CL, cl nor cL Omit leading multipliers. For example, with water of hydration enter NaSO4(H2O)2 but not NaSO4.2H2O The following abbreviations are recognized
