In order to calculate the number of moles of bromine liquid produced, we need to know the molar mass of bromine (Br). The molar mass of bromine is 79.904 g/mol.
To calculate the number of moles, we divide the mass of bromine (6.6g) by its molar mass (79.904 g/mol):
Number of moles = Mass of bromine / Molar mass of bromine
= 6.6 g / 79.904 g/mol
= 0.08255 mol
However, since the number of significant digits in the given mass is 2, we should round the final answer to 2 significant digits. Therefore, the correct answer is:
Number of moles of bromine liquid produced = 0.082 mol
A chemist measures the amount of bromine liquid produced during an experiment she finds that 6.6g of bromine liquid is produced calculate the number of moles of bromine liquid produced
Be sure your answer has correct number of significant digits in g
