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.
To make 20 moles of sodium chloride, you would need 20 moles of sodium ions and 20 moles of chloride ions. This could be achieved by combining 40 moles of sodium atoms with 40 moles of chlorine atoms to form 20 moles of sodium chloride.
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles NaOH
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
467.52 g NaCl
40 g sodium chloride are easily soluble in water.The solubility of NaCl at 100 0C is 38,99 g/100 g NaCl.
The answer is 2337,59 g NaCl.
Well the recommended amount of sodium to take per day is not more than 2300mg. So that is 2.3 grams. The atomic mass of sodium is 23.0. So the amount of sodium in moles would be 2.3/23.0 = 0.1moles
To make 20 moles of sodium chloride, you would need 20 moles of sodium ions and 20 moles of chloride ions. This could be achieved by combining 40 moles of sodium atoms with 40 moles of chlorine atoms to form 20 moles of sodium chloride.
60 g NaOH x 1 mole NaOH/40 g NaOH = 1.5 moles NaOH
To find the number of moles in 40 grams of sodium hydroxide, you first need to calculate the molar mass of NaOH. The molar mass of NaOH is about 40 g/mol. Then, you divide the given mass by the molar mass to get the number of moles. So, 40 grams divided by 40 g/mol is equal to 1 mole of NaOH.
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
To determine the number of moles in 20g of sodium hydroxide, you need to divide the given mass by the molar mass of sodium hydroxide. The molar mass of NaOH is 40 g/mol (sodium: 23 g/mol, oxygen: 16 g/mol, hydrogen: 1 g/mol). So, 20g NaOH / 40 g/mol = 0.5 moles of sodium hydroxide.
8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
To find the grams of sodium hydroxide in 0.150 mol, first calculate the molar mass of sodium hydroxide, which is approximately 40 g/mol. Then, multiply the molar mass by the number of moles: 40 g/mol x 0.150 mol = 6 grams of sodium hydroxide.
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
To calculate the mass of 2.5 moles of sodium hydroxide (NaOH), you need to know the molar mass of NaOH, which is 40 g/mol. Multiply the number of moles by the molar mass: 2.5 moles x 40 g/mol = 100 grams of sodium hydroxide.
To calculate the grams of NaCl needed to make a 0.125 M solution in 200.0 mL, use the formula: moles = Molarity x Volume (L). First, convert 200.0 mL to 0.2 L. Then, calculate moles: 0.125 mol/L x 0.2 L = 0.025 moles of NaCl. Finally, convert moles to grams by multiplying by the molar mass of NaCl (58.44 g/mol): 0.025 moles x 58.44 g/mol = 1.46 grams of NaCl.
