Explain Cm and M.
From the definition of molarity, one liter of the stated solution contains 0.256 mole of sodium bromide. The gram formula weight of sodium bromide is 102.89; therefore, one liter of the solution contains 0.256 X 102.89 or 26.34 grams. 18.7/26.34 = 0.710, the fraction of a liter that contains 18.7 grams of sodium bromide.
The unit formula for sodium bromide is NaBr. There is one sodium ion and one bromide ion. Add the atomic weights from the periodic table for sodium and bromine. This will give you the formula weight. Atomic weight Na = 22.989770 Atomic weight Br = 79.904 Formula weight NaBr= 22.989770 + 79.904 = 102.894 Save
ferric bromide or iron(III) bromide. CAS No. 10031-26-2 ((FeBr3))Molecular Formula: Br3FeMolecular Weight: 295.557
400 mls would require 40g of glucose for a 10% solution and thus 20g for a 5% solution.
Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
yes
lithium is an element that has a extremely low atomic weight and is a mineral.
244 amu
The atomic weight of bromine is 79,904 amu.
lithium 6.941
Lithium's major use today would be for batteries, because of its light weight, and energy density.
Lithium is a meta element. Atomic mass of it is 7.
