doesn't have one, its a compound. only elements have atomic numbers, which is the number of protons the element has.
Sodium chloride is a compound, not an element and hasn't an atomic number.
sodium chloride is a salt, a type of compound, not an element. it has no atomic number.
The is no atomic number for NaCl (sodium chloride) as it is a compound and atomic nuber applies to elements. NaCl is made of the two elements sodium and chlorine. Sodium's atomic number is 11. Chlorine's atomic number is 17.
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=58.5 grams20.0 grams NaCl / (58.5 grams) =.342 moles 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=58.5 grams38.0 grams NaCl / (58.5 grams) = .650 moles 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
Atomic mass of sodium = 22.99 Atomic mass of chlorine = 35.45 Total mass = 58.44g 58.44g of NaCl contains 6.023 x 1023 atoms ... 18.035g of NaCl contains 18.035x6.023x1023/58.44 = 1.858x1023 atoms!
Sodium chloride is not an atom, so it doesn't have an atomic number.
Atomic mass of NaCl = 23.0 + 35.5 = 58.5 Amount of NaCl = 746/58.5 = 12.8mol
Multiply the number of moles times the molar mass of the compound. Moles cancel and you are left with mass in grams.For example: What is the mass of 2.47 moles of sodium chloride, NaCl?Known: The molar mass of NaCl is 58.44g/mol. (Using atomic weights in grams from the periodic table.)Solution:2.47mol NaCl x 58.44g/mol NaCl = 144g NaCl
I'm going to assume that you mean 23.34g of NaCl. 1 mole NaCl = 58.442g NaCl (the atomic weight of Na and Cl in grams) 23.34g NaCl x (1mol NaCl/58.442g NaCl) = 0.3994mol NaCl
The mass of one mole of NaCl is the sum of the atomic weights for sodium and chlorine in grams. The atomic weights are found on the periodic table.
NaCl is sodium chloride. NaCl2 doesn't exist up today.
