What else can I help you with?
What is the atomic number for Nacl and what is the relationship it has to do with the periodic table?
sodium chloride is a salt, a type of compound, not an element. it has no atomic number.
What is the coordination number of NaCl?
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.
How many moles are in 20.0 grams of 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 grams20.0 grams NaCl / (58.5 grams) =.342 moles NaCl
The number of moles in 25 grams of 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
How many atoms in compound NaCl?
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!
How many moles are in 746g of NaCl?
Atomic mass of NaCl = 23.0 + 35.5 = 58.5 Amount of NaCl = 746/58.5 = 12.8mol
How mny moles are in 23.34 of 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
What is the mass of a mole of NaCl measured by?
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.
What is the number of moles in 42 g of NaCl?
To find the number of moles in 42 g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.5 g/mol (sodium's atomic weight is 23 and chlorine's is 35.5). So, 42 g / 58.5 g/mol ≈ 0.72 moles of NaCl.
Why it is formula is NaCl?
NaCl is sodium chloride. NaCl2 doesn't exist up today.
How is the mass compound determined from the number of moles?
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
How do I convert 38 grams of NaCl to moles and formula units?
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
