Answer :
Final answer:
The mass of 4.0 moles of fluorine is 76 g, which is calculated by multiplying the number of moles by the molar mass of fluorine (19 g/mol).
The correct answer is 1
Explanation:
The mass of 4.0 moles of F (fluorine) can be calculated by using the molar mass of fluorine, which is approximately 19 g/mol. To find the mass, simply multiply the number of moles by the molar mass:
Mass = moles × molar mass = 4.0 moles × 19 g/mol = 76 g
Therefore, the mass of 4.0 moles of fluorine is 76 g, which corresponds to option 1).
The correct answer is 1
