ስለዚህ መተግበሪያ
The molecular weight, or molar mass, of a compound is the mass of one mole of it in grams per mole, found by adding up the standard atomic weight of every atom in its chemical formula. This molecular weight calculator parses a formula you type — element symbols with optional subscripts, nested parentheses, and a leading multiplier for hydrates — and sums the atomic weights, drawing on IUPAC standard values (hydrogen 1.008, carbon 12.011, oxygen 15.999, and so on).
As a worked example, water H2O contains two hydrogen atoms and one oxygen: 2 × 1.008 + 15.999 = 18.015 g/mol. Glucose C6H12O6 sums to 6 × 12.011 + 12 × 1.008 + 6 × 15.999 = 180.156 g/mol. The calculator also returns a per-element breakdown showing each element’s atom count, atomic weight, mass subtotal and percentage of the total mass — so for water it reports oxygen as about 88.8% of the mass and hydrogen the rest.
The parser understands parentheses and hydrate dot-notation, so Ca(OH)2 is read as one calcium, two oxygen and two hydrogen (74.09 g/mol) and CuSO4.5H2O includes the five waters of crystallisation (249.68 g/mol). Molar mass is the essential bridge between the mass you weigh on a balance and the moles a reaction needs, so it underlies solution preparation, reaction stoichiometry, yield calculations and converting between grams and moles at every step of quantitative chemistry.

Multiply each element’s atomic weight by how many atoms of it the formula contains, then add them up. Water (H₂O) is 2 × 1.008 + 15.999 = 18.015 g/mol.

Element symbols with optional counts, nested parentheses and a leading multiplier for hydrates. Ca(OH)2 is read as one calcium, two oxygen and two hydrogen; CuSO4.5H2O includes five waters.
What is the difference between molecular weight and molar mass?

Use a dot before the water group: CuSO4.5H2O. The leading 5 multiplies the H2O, adding five waters of crystallisation, and the calculator returns 249.68 g/mol for that hydrate.
የምን ያህል በመቶ ያሳያል?
For each element it gives that element’s share of the total mass. In water, oxygen is about 88.8% and hydrogen 11.2%; in glucose, carbon is 40.0%, hydrogen 6.7% and oxygen 53.3% — useful for empirical-formula and purity work.
