The molecular mass of borax (sodium tetraborate decahydrate - Na2B4O7.10H2O) is 381,37 g.
BP is Boron phosphide (also referred to as boron monophosphide). B = Boron P = Phosphorus Its Molar mass is 41.7855 g/mol.
According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.

1 mol of bromine has 79.904g. 79.904g/mol x 350mol =
10.3224 g/mol
1 Mol Boron Atomic mass: 10.811 n = m/M therefore m = n x M = 10.811g Boron volume = mass/density = 10.811 / 2.36 = 4.5809 cm2Boron
BP is Boron phosphide (also referred to as boron monophosphide). B = Boron P = Phosphorus Its Molar mass is 41.7855 g/mol.
Boron Sulfide is a chemical compound with the formula B₂S₃. B = Boron S = Sulfur Its molar mass is 117.8 g/mol.

According to the periodic table, the atomic mass of rubidium, Rb is 85.5. This is numerically equal to the molar mass in g/mol. Therefore the mass of 1 mol of Rb is 85.5g.Mass of 1 mol means the molar mass of the element. Molar mass of Rubidium is 85.47 gmol-1. Rb is in the 1st group.
Sodium (Na) ---------------------------------------------------------------------------------------- An easier way to get that kind of answer, would just be to google it instead... (just for you to know)

65.38(4) g mol-1
Mole / Molar mass = mass = 0.118 [mol] /169.87 [g mol−1] = 20.05 grams
15.8 mol B = 9.51 X 1024 atoms.15.8 mol (6.02 X 1023/ 1 mol) = 9.5116 X 1024
