Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations:ĭefinitions of molecular mass, molecular weight, molar mass and molar 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.Ĭomputing molecular weight (molecular mass) Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg.Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Its molecular weight is 110.98 g/mol and its melting point is 772 C. Na 2SO 4(aq) + CaCl 2(aq) = CaSO 4(s) + NaCl(aq)Ĭomputing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'. Calcium chloride, CaCl2, is a typical ionic halide and is a solid at room temperature. Please let us know how we can improve this web app.CaCl 2(aq) + Na 3PO 4(aq) = Ca 3(PO 4) 2(s) + NaCl(aq)ĪgNO 3(aq) + CaCl 2(aq) = AgCl(s) + Ca(NO 3) 2(aq)ĬaCl 2(aq) + Na 2CO 3(aq) = CaCO 3(s) + NaCl(aq) Use the information and examples provided in the Exploration and the values recorded in Data Table 1 from Step 8 to. Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol. THe istructions are: Calculate how many moles of CaCl22H2O are present in 1.50 g of CaCl22H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl22H2O.Finding molar mass starts with units of grams per mole (g/mol). This means that for every mole of cacl2, there are 100.98 grams. Convert grams CaCl2 to moles - Conversion of Measurement Units. 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.Ĭomputing molecular weight (molecular mass) Do a quick conversion: 1 grams CaCl2 0.0090103077921142 mole using the molecular weight calculator and the molar mass of CaCl2. Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg Polarizability increases with: greater number of electrons more diffuse electron cloud Dispersion forces usually increase with molar mass. ![]() Computing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'.
