To find the mass of 64 moles of Cl (chlorine), you need to multiply the number of moles by the molar mass of Cl. The molar mass of Cl is approximately 35.45 g/mol. Therefore, 64 moles of Cl would be approximately 2267.2 grams (64 moles x 35.45 g/mol).
In a 50-50 mixture of Cl-35 and Cl-37, each Cl atom will have an average atomic mass of 36.5. Since Cl has 18 neutrons in Cl-35 and 20 neutrons in Cl-37, the average number of neutrons in each Cl atom will be 19. Therefore, there will be a total of 950 neutrons in 50 atoms of Cl.

Silver chloride is composed of one silver atom and one chloride atom. The molar mass of silver chloride is 143.32 g/mol and the molar mass of silver is 107.87 g/mol. Therefore, the percentage of silver in silver chloride is (107.87/143.32) x 100 = 75.3%.
There are 2 moles of Cl in 1 mole of CaCl2. The molar mass of Cl is 35.45 g/mol. So, in 435 g of CaCl2, there would be 2 moles of Cl, which is equal to 70.9 g of Cl.
To find the mass of 64 moles of Cl (chlorine), you need to multiply the number of moles by the molar mass of Cl. The molar mass of Cl is approximately 35.45 g/mol. Therefore, 64 moles of Cl would be approximately 2267.2 grams (64 moles x 35.45 g/mol).
In one mole of any element, there are 6.022*1023 atoms, Avogadro's number.3 mol Cl * (6.022*1023 atoms Cl/mol Cl) = 1.8066*1024 atoms ClTherefore, there are approximately 1.807*1024 atoms in three moles of chlorine.Be careful with this answer because the question probably carries hidden in it the expectation that you know that chlorine gas is diatomic. If that is the case, what is really being asked is how many atoms are in 3 moles of chlorine gas. When you answer that question be certain that you clarify your understanding. 3 moles of chlorine gas (Cl2) has 6 moles of chlorine atoms. 6 x NA will give you the answer.
Molar mass of Cl = 35.453g/mol 1mol Cl atoms = 6.022 x 1023 atoms (1.7 x 1022 atoms Cl) x (1mol/6.022 x 1023 atoms) x (35.453g/mol) = 1.0g Cl
C = 12 grams/mole Cl = 35.45 grams/mole CCl4 = 12 + (35.45)x4 = 153.8 grams/mole 153.8 grams/mole / 6.022 x 1023 things/mole = 25.4 x 10-23 grams/thing where thing in this case would be a molecule of CCl4
For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023. AlCl3= 133.5 grams10.5 grams Cu / (133.5 grams) × (6.02 × 1023 atoms) = 4.73 × 1022 atoms
In a 50-50 mixture of Cl-35 and Cl-37, each Cl atom will have an average atomic mass of 36.5. Since Cl has 18 neutrons in Cl-35 and 20 neutrons in Cl-37, the average number of neutrons in each Cl atom will be 19. Therefore, there will be a total of 950 neutrons in 50 atoms of Cl.
To find the mass of iodine containing the same number of atoms as 25.0 grams of chlorine, we can first calculate the number of moles of chlorine using its molar mass (Cl: 35.45 g/mol). Next, using the mole ratio of chlorine to iodine (1:1), we can determine the number of moles of iodine. Finally, we can convert the moles of iodine to grams using the molar mass of iodine (I: 126.90 g/mol) to find the mass of iodine.

The element with an atomic mass of 35.453 grams is chlorine. It is a halogen gas with the chemical symbol Cl and atomic number 17.
The molecular formula for lithium chlorate is Li₂ClO₃, which consists of two lithium (Li) atoms, one chlorine (Cl) atom, and three oxygen (O) atoms. Given the molar mass of 73.8 grams/mole, this is consistent with the calculated molar mass of Li₂ClO₃, which is approximately 73.89 grams/mole. Thus, the molecular formula is indeed Li₂ClO₃.
Silver chloride is composed of one silver atom and one chloride atom. The molar mass of silver chloride is 143.32 g/mol and the molar mass of silver is 107.87 g/mol. Therefore, the percentage of silver in silver chloride is (107.87/143.32) x 100 = 75.3%.
Aluminum trichlorate is made up of one aluminum, three chlorine and nine oxygen atoms. By mass, chlorine makes up 38.35 percent of the total 277.33 grams per mole.
