Question

A chemist measures the amount of fluorine gas produced during an experiment. He finds that 482. g of fluorine gas is produced.

Calculate the number of moles of fluorine gas produced.

Be sure your answer has the correct number of significant digits.

Answer 1

Answer: 25.37055324733817mol

Approximately 25.371mol

Explanation: Number of moles of a substance is the mass of that substance containing the same amount of fundamental units, for instance atom in 12.0g of 12°C

Therefore:

Number of moles= mass/ molecular mass

Where mass of fluorine given= 482g

Standard Molecular mass of fluorine= 18.9984032g/mol

Substituting value in equation

Mole= 482g/18.9984032g/mol = 25.37055324733817mol

Approximately : 25.371mol
