This is slightly less chlorine than required to maintain 'chemical pasteurization” of an Olympic-size non-comercial pool. Restated: for each mol of Cl 2 there are 70.90 grams of Cl 2.* This is the gram molecular mass and it equals 1 mol: 70.90g of Cl 2 = 1 mol. Convert to gram mass (by multiplying by 1g). The Relative atomic mass of diatomic Chlorine is 70.90. (Note that diatomic forms are considered molecules). Multiply the Relative atomic mass by this subscript value (2): 35.45 *2 = 70.90. This condition is indicated by the subscript. Calculate the number of moles of chlorine present in 140 g of chlorine gas. Question: In the gaseous state, chlorine exists as a diatomic molecule Cl2 (Molar mass 70.9 g/mol). Pure Chlorine, in the gas state, usually exists in a diatomic form (Cl 2). This problem has been solved You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Look up the Relative atomic mass (aka Standard atomic weight) of Cl (Chlorine).

This constant is the number of atoms or molecules per molar mass of an element or compound.ĥ.0*10E 26 molecules (Cl 2)/ 6.022141E 23/mol = 830.3 mols of Cl 2 Any science question, which relates to applied mathematics is reasonable.ĭivide the quantity of the molecules by Avogadro constant (currently: 6.022141E 23/mol).

(Greetings Alan, It is diatomic Chlorine, not carbon). And I know that in 58.How many grams are in 5.0*10^26 molecules of Cl2 And I'm going to convert that to grams of sodium chloride. So two moles of sodium chloride in every two moles of sodium, Which will give me 1.099 moles of sodium chloride and then going to take that moles of sodium chloride. And I use four significant digits since my Mass had four significant digits, then I'm going to take my 1.099 moles of sodium and knowing and for every two sodium, there's two sodium chloride. Knowing that in one mole of sodium We have 22.98 g Which is going to give me 1.099 moles of sodium. So the first thing I'm going to do is convert my sodium two moles of sodium. So I'm going to follow through using sodium first.

I'm going to work out the amount of sodium chloride I will get produced if all the sodium reacts. We need to figure out which one is the limiting reactant to do that. Knowing all that we can then calculate because we are given the mass of two different chemicals. We have also discussed above that chlorine exists as a diatomic molecule. We were told this one has a 22.98 grams per mole, 70.90 g per mole. We know that the atomic mass of chlorine is 35.5 g/mole. The molar mass of Cl 2 (which we get from the atomic mass of Cl from the periodic table) is 70.90 g/mol. We were also told the molar mass of each compound. And we're looking for the amount of sodium chloride. We are told we have 25.25 g of sodium And we're told we have 30.5 g of chlorine. Given the reaction of two sodium reacting with chlorine gas giving you to sodium chloride.
