20 moles of elemental sodium and 10 moles of elemental chlorine, which contains two atoms per molecule.
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.
The molar mass of sodium is approximately 23 g/mol. Therefore, 20 grams of sodium would be equivalent to about 0.87 moles of sodium.
First write down the BALANCED reaction equ'n. NaOH + HNO3 = NaNO3 + H2O We note the molar ratios are all ' 1:1 :: 1:1. So correspondingly 20 moles(HNO3) requires 20 moles (NaOH). By ratio 1:1 :: 20:20 NB By correspondence, the reaction will produce 20 moles (NaNO3) and 20 moles(Water/H2O). 20:20 :: 20:20
The amount of sodium chloride that would dissolve in 2 L of water at 20 degrees Celsius depends on if the water is moving. It would dissolve faster in moving water than still sitting water.
Chlorine is an element. It has 17 protons, 18 or 20 neutrons, and, in its neutral state, 17 electrons. It is produced by the electrolysis of sodium chloride.
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.
To find the number of moles of strontium chloride in 20 mL of a 0.2 M solution, you can use the formula: moles = concentration (M) × volume (L). First, convert 20 mL to liters, which is 0.020 L. Then, calculate the moles: 0.2 moles/L × 0.020 L = 0.004 moles of strontium chloride.
At 20 0C the solubility of sodium chloride in water is approx. 360 g/L.
pure sodium chloride is white
Sodium chloride is very soluble in water - 360,9 g/L at 20 0C.
Sodium Chloride is white crystalline solid at room temperature
Sodium chloride is very soluble in water: 360,9 g/L at 20 0C.
The solubility of sodium chloride in water is approx. 360 g/L at 20 0C.
Sodium chloride is very soluble in water - approx. 360 g/L at 20 0C.
Divide the amount of sodium chloride by the total amount (sodium chloride + water). Then multiply that by 100 to convert to percent.
The solubility of sodium chloride in water is 360,0 g/L at 20 0C.
The molar mass of sodium is approximately 23 g/mol. Therefore, 20 grams of sodium would be equivalent to about 0.87 moles of sodium.
