there are four boron atoms in borax
the molecular weight of boron is 10.811g/mol
to convert to molecules -> moles times avagadro's number (6.023 x 10^23)
->> 4 x 6.023 x 6.023 x 10^23 = 2.4092 x 10^24 (you can carry it to this many significant figures because 4 and avagadro's number [6.023 x 10^23] are exact/absolute number)
There are 4 boron atoms in a molecule of borax, which has the chemical formula Na2B4O7·10H2O.
There are 17 elements in a molecule of borax: sodium (Na), boron (B), oxygen (O), and hydrogen (H).
To calculate the number of moles in 20g of borax (Na2B4O7), we first need to find the molar mass of borax. By adding the atomic masses of all the elements in borax, we get a molar mass of approximately 201.22 g/mol. Then, we use the formula: moles = mass / molar mass. Substituting in the values, we find that there are approximately 0.10 moles of borax in 20g. Since there are four boron atoms in one molecule of borax, the number of moles of B (boron) would be 0.10 moles * 4 = 0.40 moles.
One teaspoon of borax weighs about 4.9 grams.
Borax, also known as sodium borate, sodium tetraborate, or disodium tetraborate, is an important boron compound, a mineral, and a salt of boric acid. It is usually a white powder consisting of soft colorless crystals that dissolve easily in water.There are no water molecules in borax.
Borax has two sodium atoms.
The borax decahydrate - Na2B4O7.10 H2O has 20 H atoms in the molecule.
There are 4 boron atoms in a molecule of borax, which has the chemical formula Na2B4O7·10H2O.

Borax - Na2B4O7 - contain two sodium atoms.
Borax (Na2B4O7) has two sodium atoms in the formula unit.
A molecule of borax, Na2B4O7, contains a total of 13 atoms. This can be calculated by adding the number of each type of atom present in the molecule: 2 sodium atoms (Na), 4 boron atoms (B), and 7 oxygen atoms (O), for a total of 13 atoms. Each element's subscript in the chemical formula indicates the number of atoms of that element in the molecule.
There are 432 Na4 B17 O (7 in the Na2B4O7 and 10 in the hydrating H2O)20 H (in the hydrating H2O)

Since there are four boron atoms in one molecule of borax, the number of moles of B (boron) would be 0.10 moles * 4 = 0.40 moles.
yes.you can buy borax in australia.i buy mine in many hardware stores but, not all of them sell borax.
