Because it ionizes into Na+ and Cl-, thus ONE mole or molecule of NaCl produces TWO moles or molecules, namely Na and Cl, thus i (the van't Hoff factor) is 2.
2
The expected value for 'i' is 2 for NaCl because it dissociates into two ions (Na+ and Cl-) when dissolved in water. This means one formula unit of NaCl produces 2 ions in solution.
This value is 36.
NaCl has not 2 in the formula unit.
This value is approx. 36.
NaCl
For this you need the atomic (molecular) mass of NaCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. NaCl=58 grams 25.0 grams NaCl / (58 grams) = .431* moles NaCl *approximation
That refers to a mixture consisting of 2/100 of sodium chloride (salt) and 98/100 of something else (usually water).
The molar ratio of Cl2 to NaCl is 1:2, so for every 1 mole of Cl2, 2 moles of NaCl are produced. To find the amount of NaCl produced from 13g of Cl2, first calculate the number of moles of Cl2 using its molar mass, then use the mole ratio to determine the moles of NaCl, and finally convert to grams of NaCl.
This value is 36,79 kJ/mol.
If 2 moles of Na2CrO4 react completely, they will form the same number of moles of NaCl. This is because the mole ratio between Na2CrO4 and NaCl is 1:2. Therefore, 2 moles of Na2CrO4 will form 2 moles of NaCl.
The formula unit of NaCl (sodium chloride) contain 2 atoms.
