Well, there are 140 grams of 2Cl2 in one mole of it. You take the Atomic Mass and find how many atoms and multiply them together. Chlorine has an atomic mass of about 35, so multiply by four b/c there are four Cl atoms in 2Cl2 .
We assume that the quantity 56.22 is in grams. The formula mass of CF2Cl2 is 12.0 + 2(19.0) + 2(35.5) = 121.0Amount of CF2Cl2 = mass of pure sample/molar mass = 56.22/121.0 = 0.465mol There are 0.465 moles of CF2Cl2 in a 56.22 pure sample.
The name of CF2Cl2 is dichlorodifluoromethane.
A common name for CF2Cl2 is dichlorodifluoromethane, which is also commonly known as CFC-12.
The molecular shape of CF2Cl2 is tetrahedral. The carbon atom is at the center, with two fluorine atoms and two chlorine atoms attached, resulting in a symmetrical tetrahedral shape.
this is a easy one. There are only 0.04166 moles.

To find the number of moles in 1 kg of CF2Cl2, you first need to calculate the molar mass of CF2Cl2. Carbon has a molar mass of 12.01 g/mol, fluorine has a molar mass of 19.00 g/mol, and chlorine has a molar mass of 35.45 g/mol. Adding these up gives a molar mass of 120.91 g/mol for CF2Cl2. Next, convert 1 kg to grams (1000 g). Finally, divide 1000 g by the molar mass of CF2Cl2 to find the number of moles in 1 kg of CF2Cl2.
The name of CF2Cl2 is dichlorodifluoromethane.

A common name for CF2Cl2 is dichlorodifluoromethane, which is also commonly known as CFC-12.
CF2Cl2
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
The molar mass, that is mass per mole is given in the periodic table. The mass of one Cl-atom is approximately 35,45g/mole. In Cl2 there are 2, henbce you multiply the molar mass with 2.
Of course 6 moles.
16 grams of oxygen how many moles is 0,5 moles.
moles of what?
55.8 moles
