計算 the molecular weight (molar mass) of any chemical formula instantly. Supports parentheses, hydrates, と displays element composition breakdown. 純粋な クライアントサイド, no server needed.
This molecular weight計算機 computes the molar mass of any chemical formula instantly in your browser. It supports standard chemical notation including parentheses for complex compounds と the dot notation for hydrates (e.g., CuSO₄·5H₂O). The計算機 uses standard atomic weights from the IUPAC と displays a detailed breakdown of each element's contribution to the total mass. すべて calculations happen クライアントサイド — データはサーバーに送信されません.
Molecular weight (also called molar mass or molecular mass) is the sum of the atomic weights of all atoms in a molecule. It is expressed in grams per mole (g/mol) と is essential for stoichiometric calculations in chemistry.
Simply type the formula as you would write it. For example, calcium nitrate is Ca(NO3)2, と aluminum sulfate is Al2(SO4)3. The計算機 automatically handles the multiplication of atoms inside parentheses.
はい! Use the dot notation for water molecules in hydrates. For example, copper(II) sulfate pentahydrate is CuSO4.5H2O or CuSO4·5H2O. The計算機 will include the mass of water molecules in the total.
This計算機 uses standard atomic weights from the IUPAC (International Union of 純粋な と Applied Chemistry) for the most common isotopes. The values are rounded to 4 decimal places for precision.
