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.
To find the number of moles of sodium chloride in a 250 mL solution with a concentration of 1.20 m, you can use the formula: moles = concentration (mol/L) × volume (L). First, convert 250 mL to liters, which is 0.250 L. Then, multiply: 1.20 mol/L × 0.250 L = 0.30 moles of sodium chloride.
There are 4.5 moles of sodium fluoride in 4.5 moles of sodium fluoride.
To calculate the number of moles in a solution, use the formula: moles = Molarity x Volume (in liters). First, convert the volume from milliliters to liters by dividing by 1000 (250 mL = 0.25 L). Then, plug the values into the formula: moles = 1.20 mol/L x 0.25 L = 0.30 moles of sodium chloride.
The answer is 48,17 L.
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.
One mole of sodium chloride is composed of one mole of sodium atoms. Therefore, 3.6 moles of sodium chloride would require 3.6 moles of sodium.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
There are 10.5 moles of sodium in 5.25 moles of Na2SO4 because there are 2 sodium atoms in one formula unit of Na2SO4.
The answer is 0,175 moles.
55.0 moles of sodium are equal to 1 264,44 g.
