What number of chlorine atoms are there in 12.2 g of ccl4? what number of chlorine atoms are there in 12.2 of ? 4.77×1022 atoms?
– atoms. Answer:- We now have been given the grams of carbon tetrachloride and requested to calculate the variety of atoms of chlorine. It’s a three step conversion drawback. Within the first we convert the grams of carbon tetrachloride to moles of it. In second step we convert moles of carbon tetrachloride to moles of chlorine and within the third step we convert the moles of chlorine to atoms of chlorine. For grams to mole conversion we’d like the molar mass of the compound. Molar mass of carbon tetrachloride is 153.82 grams per mol. If we have a look at the formulation of carbon tetrachloride then 4 chlorine are current in it. It means 1 mol of carbon tetrachloride has 4 moles of chlorine. The calculations are as follows: = atoms So, there are atoms in 12.2 grams of .
There are of chlorine in 12.2 g of .
The variety of moles of is calculated by the next formulation:
…… (1) The mass of is 12.2 g.
The molar mass of is 153.82 g/mol.
Substitute these values in equation (1).
The variety of models which are current in a single mole of the substance is decided by Avogadro’s quantity. It has a numerical worth of . These models might be electrons, atoms, molecules or ions, relying on the character of the substance.
The formulation of carbon tetrachloride signifies that one mole of has 4 moles of Cl in it.
Due to this fact the variety of moles of chlorine might be calculated as follows:
One mole of Cl has of Cl. Due to this fact the variety of atoms of Cl might be calculated as follows:
Due to this fact there are of chlorine in 12.2 g of .

12 Rationalization: There are 3 in a single molecule. 3 x 4 = 12
38 chlorine atoms are in 3 molecules of HCI Rationalization:
Choice (c) is the proper reply. Rationalization: A response equation by which there are equal variety of reactant and product molecules is called a balanced equation. For instance, Variety of atoms on reactant aspect are as follows. Al = 2 = 3 Cl = 6 Variety of atoms on product aspect are as follows. Al = 1 = 1 Cl = 3 Due to this fact, to steadiness this equation multiply by 2 and by 3 on product aspect. Therefore, the balanced chemical equation is as follows. Thus, we are able to conclude that variety of complete chlorine atoms on product aspect are 6.
38 chlorine atoms are in 3 molecules of HCI
Reply Calcium chloride has the molecular formulation from which we are able to say that one molecule of calcium chloride consist of 1 atom of calcium and two atoms of chlorine. given : 2 mol of complete moles of chlorine atoms = variety of atoms in a single mole × variety of formulation models= 2×2= 4 Complete variety of atom = Complete variety of moles × Avogadro quantity So, complete variety of chlorine atoms = 4 × 6.0221× =2.4088× atoms
The reply is D. 6 you multiply 2 and three
The variety of formulation models of NaCl are 7. In 1 mole of NaCl there are formulation unit are current. Thus, 1 formulation unit will probably be there in moles. and, 7 formulation unit will probably be there in moles. There may be 1 mol of Cl current in 1 mol of NaCl. thus, of Cl will probably be there in mol of NaCl. Changing variety of moles into variety of atoms as follows: In 1 mole of a substance there are atoms of chlorine thus, in mol there will probably be 7 atoms of chlorine. Due to this fact, variety of atoms of chlorine will probably be 7.
