Final answer:
To find the mass of Fluorine in 1.25 moles, multiply the number of moles by the molar mass of Fluorine (19.00 g/mol), resulting in 23.75 grams of Fluorine.
Step-by-step explanation:
The mass of Fluorine in 1.25 moles can be calculated using the molar mass of Fluorine. The atomic weight of Fluorine is approximately 19.00 grams per mole. Therefore, to find the mass of 1.25 moles, you would multiply the number of moles by the molar mass:
1.25 moles × 19.00 g/mol = 23.75 grams.
So, the mass of Fluorine in 1.25 moles is 23.75 grams. This step-by-step calculation ensures the precision of your Chemistry assignments.
