mass of 8.39*10^23 molecules of flourine
To calculate the mass of 8.39*10^23 molecules of fluorine, we first need to find the molar mass of fluorine. The molar mass of fluorine is 18.998 g/mol.
1 mol of fluorine = 18.998 g
1 molecule of fluorine = 18.998 g/6.022*10^23 molecules
8.39*10^23 molecules of fluorine = (18.998 g/6.022*10^23 molecules) * 8.39*10^23 molecules
Simplifying the above expression:
8.39*10^23 molecules of fluorine = 26.74 g
Therefore, the mass of 8.39*10^23 molecules of fluorine is 26.74 g.
To find the mass of a given number of molecules of a compound, you'll need to know the molar mass of that compound. In this case, we need to find the mass of 8.39 * 10^23 molecules of fluorine (F₂).
Step 1: Find the molar mass of fluorine (F₂).
The molar mass of fluorine (F) is 19.0 g/mol.
Step 2: Calculate the mass of 1 molecule of F₂.
Since each molecule of F₂ contains 2 fluorine atoms, the molar mass of F₂ is 2 times the molar mass of F.
Mass of 1 F₂ molecule = 2 * 19.0 g/mol = 38.0 g/mol.
Step 3: Calculate the mass of 8.39 * 10^23 molecules of F₂.
To find the mass, multiply the number of molecules by the mass of 1 molecule.
Mass of 8.39 * 10^23 molecules of F₂ = (8.39 * 10^23) * (38.0 g/mol).
Now, you can calculate the final result by multiplying the number of molecules by the molar mass:
Mass of 8.39 * 10^23 molecules of F₂ = (8.39 * 10^23) * (38.0 g/mol) = 3.1818 * 10^25 g.
Therefore, the mass of 8.39 * 10^23 molecules of fluorine is approximately 3.1818 * 10^25 grams.
