Lithium Bromide : LiBr.
Molar mass of lithium bromide : 86.845 g/mol.
To find the mass of 2.6 mol of lithium bromide, simply multiply in order to cancel out the moles : 2.6 mol * 86.845 g / 1 mol = 225.8 grams.
Explanation:
In any chemical change, one or more initial substances change into a different substance or substances. ... According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and kind of atoms after the chemical change as were present before the chemical change
Example:
The carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change.
