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
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
To calculate the number of moles of bromine liquid produced, we need to use the formula:
moles = mass / molar mass
The molar mass of bromine is 79.9 g/mol.
Plugging in the values, we have:
moles = 6.6 g / 79.9 g/mol
Calculating this, we get:
moles ≈ 0.0826 mol
Therefore, the number of moles of bromine liquid produced is approximately 0.0826 mol.
To calculate the number of moles of bromine liquid produced, we need to use its molar mass. The molar mass of bromine (Br) is approximately 79.9 g/mol.
To find the number of moles, we divide the mass of the bromine liquid produced by its molar mass:
Number of moles = Mass / Molar mass
Number of moles = 6.6 g / 79.9 g/mol
Now we can calculate the value:
Number of moles = 0.0826 mol
Therefore, the number of moles of bromine liquid produced is 0.0826 mol.
