One mole of CH2F2 has a mass of (12.011)+2(1.0079)+2(18.9984) g = 52.0236 g
19 g of CH2F2 is equivalent to 19/52.0236 moles = 0.3652 moles
For every mole of CH2F2 there are 2 F atoms, and 1 mole of a substance has 6.022 x 10^23 entities.
So 19 g of CH2F2 has 2(0.3652)(6.022 x 10^23) F atoms = 4.40 x 10^23 F atoms.

How many F atoms are needed to occupy the same volume as a Cs atom?
Since the volume of an atom is determined by the radius of its electron cloud, we can use the atomic radius to approximate the volume each atom occupies. The atomic radius of Cs is larger than that of F, so more F atoms would be needed to occupy the same volume as one Cs atom. Approximately 9 F atoms are needed to occupy the same volume as one Cs atom.
What is the lLewis structure of CH2F2?
The Lewis structure of CH2F2 is represented as H-C-H with a double bond to C and a single bond to F on each side of the C atom. This arrangement allows each atom to have a full valence shell and minimizes formal charges.
How many moles are in 1.01e23 F atoms?
To find the number of moles in 1.01e23 fluorine atoms, divide the given number of atoms by Avogadro's number, which is approximately 6.022e23. So, 1.01e23 F atoms / 6.022e23 atoms/mol ≈ 0.168 moles of F atoms.

How many moles in 76 grams of fluorine?
To find the number of moles in 76 grams of fluorine, you first need to determine the molar mass of fluorine, which is approximately 19 grams per mole. Then, you divide the given mass (76 grams) by the molar mass of fluorine to get the number of moles. In this case, 76 grams of fluorine is equal to approximately 4 moles.
