Ni Dmg 2 Boiling Point

Molar Mass, Molecular Weight and Elemental Composition Calculator

Dimethylglyoxime DMG, (CH3CNOH)2 is used as a reagent to precipitate nickel ion. Assume that 53.0 g of DMG has been dissolved in 52.5 g of ethanol (C2H5OH). The red, insoluble compound formed between nickel(II) ion and dimethylglyoxime (DMG) is precipitated when DMG is added to a basic solution of Ni^2. CONFIRMATORY TESTS. Gently heat the solution to near the boiling point. Do not allow the solution to splatter onto the litmus paper. The paper should turn blue from ammonia fumes. Add 2 or 3 drops of dimethylglyoxime reagent (DMG). A rose-red precipitate of Ni(DMG) 2 should form. Silver, Ag + To 10 drops of solution, add 6.

Molar mass of Ni(dmg)2 is 288.9146 g/mol

Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:

Any chemical element. 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.
Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
parantesis () or brackets [].
Common compound names.

Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.
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)

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.

Definitions of molecular mass, molecular weight, molar mass and molar weight

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.
