How Many Moles Of Bromine Gas Are In 37.7 Grams?


Answer:
If the molecular mass of an element is expressed in grams, it is called one mole. The molar mass of bromine atom is 79.904 g/ mol. Bromine atom have seven electrons in its outer most shell, so it is highly reactive. Bromine gas is always present contained by diatomic form. The molar mass of bromine gas is 2* 79.904g/mol.

molar mas of bromine gas= 2 * 79.904 g/mol

moles= mass/ molar mass

moles= 37.7g/2 * 79.904 g/mol

moles= 37.7/ 159.808

moles= 0.236 moles approx
