The molecular mass of sodium chloride (NaCl) can be calculated by adding the atomic masses of sodium (Na) and chlorine (Cl). Sodium has an Atomic Mass of approximately 22.99 g/mol, and chlorine has an atomic mass of about 35.45 g/mol. Therefore, the molecular mass of NaCl is approximately 58.44 g/mol.

Can atomic and molecular ions be cations or anions?
Yes. Example of atomic cation is Na+. Example of atomic anion is Cl-. Example of molecular cation is NH4+. Example of molecular anion is NO3-.
How would you prepare a 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water?
You prepare a solution by dissolving a known mass of solute into a specific amount of solvent. In solutions, M is the molarity, or moles of solute per liter of solution. For 300 ml of a 0.1 M Na CL solution from a solid Na CL solution and water you need water and sodium chloride.
What is the mass number of NaCl?
The mass number of NaCl cannot be determined because there are two different elements involved: sodium (Na) and chlorine (Cl). Each element has its own unique mass number based on the sum of protons and neutrons in its nucleus.
What is the molecular mass of Cl 2?
The atomic mass of chlorine is 35.5. A chlorine molecule has two chlorine atoms. Therefore its molecular mass is 71u.
What is molecular mass of zncl2?
The molecular mass of ZnCl2 (zinc chloride) is calculated by adding the atomic masses of the elements in the compound. The atomic mass of zinc (Zn) is approximately 65.38 g/mol and the atomic mass of chlorine (Cl) is approximately 35.45 g/mol. Therefore, the molecular mass of ZnCl2 is approximately 136.33 g/mol.

If you wanted to combine equal numbers of Na and Cl in a flask how much Cl would you have to add if you added twenty three g of Na?
You would need to add 35.5 g of Cl to combine with 23 g of Na. This is because Na and Cl combine in a 1:1 ratio by mass based on their atomic weights (Na = 23 g/mol, Cl = 35.5 g/mol).
What are the formula weight of NaCl and BaCl2?
The molecular weight of NaCl is 58.44g/mol, the atomic mass of Na is 22.99 and the atomic mass of Cl is 35.45 when added together we get 58.44 g/mol.The molecular weight of BaCl2 is 208.233g/mol, the atomic mass of Ba is 137.327 and the atomic mass of Cl2 is (35.453)(2) = 70.906 when added together we get 208.233g/mol
What is the percentage composition of NaCl?
Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) * Calculate the molecular mass (MM):MM = 22.99 + 35.45 = 58.44 * Calculate the total mass of Na present:1 Na is present in the formula, mass = 22.99 * Calculate the percent by weight of Na in NaCl:%Na = (mass Na ÷ MM) x 100 = (22.99 ÷ 58.44) x 100 = 39.34% * Calculate the total mass of Cl present:1 Cl is present in the formula, mass = 35.45 * Calculate the percent by weight of Cl in NaCl:%Cl = (mass Cl ÷ MM) x 100 = (35.45 ÷ 58.44) x 100 = 60.66% The answers above are probably correct if %Na + %Cl = 100, that is,39.34 + 60.66 = 100.
