Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
5,25 moles (in anhydrous sodium sulphate)
There are two moles of sodium ions in two moles of sodium chloride.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
Atomic Weight sodium = 23 so 46/23 = 2 moles of sodium in 46.0g
The formula mass of sodium carbonate, Na2CO3 is 2(23.0)+12+3(16) = 106.0Amount of sodium carbonate = mass of sample / formula mass = 4/106.0 = 0.0377mol
The answer is 0,111 moles.
Every formula unit of sodium chloride has one sodium atom. Therefore, there are 4.0 moles of sodium ions in 4.0 moles of NaCl.
3.6
there are 4.5 moles
How many formula units of sodium acetate are in 0.87 moles of sodium acetat
Sodium in its elemental form is just sodium metal, Na. Thus assuming that the sample of sodium is pure, there are 2.50 moles of sodium in a 2.50mol sample.
5,25 moles (in anhydrous sodium sulphate)
There are two moles of sodium ions in two moles of sodium chloride.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
The answer is 0,175 moles.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
