The weight of a heavy water molecule, however, is not very different from that of a normal water molecule, because about 89% of the mass of the molecule comes from the single oxygen atom rather than the two hydrogen atoms. Heavy water is not radioactive. In its pure form, it has a density about 11% greater than water but is otherwise physically ...
Like other iron oxalates, ferrous oxalates feature octahedral Fe centers. The dihydrate FeC 2 O 4 (H 2 O) x is a coordination polymer, consisting of chains of oxalate-bridged ferrous centers, each with two aquo ligands.

The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula HO−C(=O)−C(=O)−OH, also written as (COOH) 2 or (CO 2 H) 2 or H 2 C 2 O 4.It is the simplest dicarboxylic acid.
Disodium phosphate (DSP), or disodium hydrogen phosphate, or sodium phosphate dibasic, is an inorganic compound with the chemical formula Na 2 H P O 4.It is one of several sodium phosphates.

A common vanadium phosphate is VOPO 4 •2H 2 O. . Seven polymorphs are known for anhydrous VOPO 4, denoted α I, α II, β, γ, δ, ω, and ε. [a] [1] [2] [3] These materials are composed of the vanadyl group (VO) and phosphate (PO 4 3−).
