The answer is it's Atomic Mass converted to grams...
Chlorine has an atomic mass of 35.45
So 1 mol of chlorine would be 35.45g
you have 142g of it, so you divide 142 by 35.45 and get 4.005 moles of chlorine

When 4 moles of aluminum react with an excess of chlorine gas, 4 moles of aluminum chloride are produced. This is because the balanced chemical equation for the reaction is: 2Al + 3Cl2 -> 2AlCl3 This means that 2 moles of aluminum react with 3 moles of chlorine gas to produce 2 moles of aluminum chloride, so 4 moles of aluminum will produce 4 moles of aluminum chloride.
You can determine the moles of HCl formed by using a balanced chemical equation for the reaction between hydrogen gas and chlorine. Calculate the stoichiometric ratio of hydrogen to HCl in the balanced equation to determine the moles of HCl formed from the given moles of hydrogen gas.
The molar mass of chlorine gas (Cl₂) is about 71 g/mol. Therefore, the mass of 0.560 moles of chlorine gas would be: 0.560 moles * 71 g/mol = 39.76 grams
To calculate the number of moles of chlorine gas, you need to divide the number of atoms by Avogadro's number. Thus, 9.02 x 10^23 atoms of chlorine gas is equal to 1.5 moles.
Since chlorine gas is a diatomic molecule (Cl2), one mole of chlorine gas contains two moles of chlorine atoms. Therefore, 6.00 moles of chlorine atoms would be equivalent to 3.00 moles of chlorine gas.

To calculate the number of moles in 15g of chlorine gas, you need to use its molar mass. The molar mass of chlorine is approximately 35.5 g/mol. Divide the given mass by the molar mass to find the number of moles. For 15g of chlorine gas, you will have about 0.42 moles.
To find the number of moles of hydrogen gas, we first need to calculate the number of moles of chlorine gas using the ideal gas law formula (PV = nRT). Once we have the moles of chlorine gas, we can determine the moles of hydrogen gas needed for the reaction. In this case, the stoichiometry of the reaction states that 1 mole of chlorine gas reacts with 1 mole of hydrogen gas, so the required moles of hydrogen gas will be equal to the moles of chlorine gas.
When 4 moles of aluminum react with an excess of chlorine gas, 4 moles of aluminum chloride are produced. This is because the balanced chemical equation for the reaction is: 2Al + 3Cl2 -> 2AlCl3 This means that 2 moles of aluminum react with 3 moles of chlorine gas to produce 2 moles of aluminum chloride, so 4 moles of aluminum will produce 4 moles of aluminum chloride.
You can determine the moles of HCl formed by using a balanced chemical equation for the reaction between hydrogen gas and chlorine. Calculate the stoichiometric ratio of hydrogen to HCl in the balanced equation to determine the moles of HCl formed from the given moles of hydrogen gas.
The molar mass of chlorine gas (Cl₂) is about 71 g/mol. Therefore, the mass of 0.560 moles of chlorine gas would be: 0.560 moles * 71 g/mol = 39.76 grams
To calculate the number of moles of chlorine gas, you need to divide the number of atoms by Avogadro's number. Thus, 9.02 x 10^23 atoms of chlorine gas is equal to 1.5 moles.
When salt (NaCl) is split by electrolysis, one mole of sodium (Na) and one mole of chlorine (Cl2) gas are produced. The molar mass of NaCl is 58.44 g/mol, so 40.0 g of NaCl is approximately 0.68 moles. Therefore, 0.68 moles of chlorine gas are produced.
There are 6.022 x 10^23 atoms in 1 mole of any element, including chlorine. Therefore, in 1.00 moles of chlorine gas, there will be 6.022 x 10^23 atoms of chlorine.
The molar mass of chlorine gas (Cl2) is 70.91 g/mol. To convert grams to moles, you divide the mass (84 g) by the molar mass (70.91 g/mol). So, 84 grams of chlorine gas is equal to approximately 1.18 moles.
The balanced chemical equation for the reaction between chlorine gas and sodium is: 2Na + Cl2 -> 2NaCl Using the equation, we can see that 1 mole of chlorine gas (Cl2) reacts with 2 moles of sodium (2Na). To calculate the mass of chlorine gas needed to react with 92 grams of sodium, first convert 92 grams of sodium to moles, then use the mole ratio from the balanced equation to find the moles of chlorine gas needed. Finally, convert the moles of chlorine gas to grams.
