Molecular mass of NaCl = 23.0 + 35.5 = 58.5
Amount of NaCl = 42/58.5 = 0.718mol
To calculate the number of moles in 25 grams of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 25 grams of NaCl is equivalent to approximately 0.43 moles.
To determine the number of moles of NaCl, you need to know the mass of NaCl you have and the molar mass of NaCl (58.44 g/mol). You can then use the formula moles = mass / molar mass to calculate the number of moles of NaCl.
13(g) / 58.5(g/mol) = 0.22 mol NaCl
To determine the number of moles in 50g of NaCl, you first need to find the molar mass of NaCl, which is approximately 58.44 g/mol. Then, you divide the given mass by the molar mass to find the number of moles. So, 50g of NaCl represents approximately 0.855 moles (50g / 58.44 g/mol = 0.855 mol).
To determine the number of moles in 1.0 kilogram of NaCl, we first need to calculate the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Next, we convert the mass of NaCl from kilograms to grams (1.0 kg = 1000 g). Finally, we divide the mass in grams by the molar mass to find the number of moles. Therefore, there are approximately 17.1 moles of NaCl in 1.0 kilogram.
To calculate the number of moles in 25 grams of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 25 grams of NaCl is equivalent to approximately 0.43 moles.

To calculate the number of moles in 23.34 g of NaCl, you first need to determine the molar mass of NaCl, which is approximately 58.44 g/mol. Then, you divide the mass given by the molar mass to find the number of moles. In this case, 23.34 g divided by 58.44 g/mol equals approximately 0.4 moles of NaCl.
To determine the number of moles of NaCl, you need to know the mass of NaCl you have and the molar mass of NaCl (58.44 g/mol). You can then use the formula moles = mass / molar mass to calculate the number of moles of NaCl.
To determine the number of moles of NaCl in a crystal of halite (NaCl), you first need to find the molar mass of NaCl, which is approximately 58.44 g/mol. Divide the given mass of 5.88 g by the molar mass to find the number of moles. So, 5.88 g / 58.44 g/mol = 0.1 moles of NaCl.
13(g) / 58.5(g/mol) = 0.22 mol NaCl
To find the number of moles in 20.0 grams of sodium chloride (NaCl), divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol. Number of moles = 20.0 g / 58.44 g/mol = 0.342 moles of NaCl.
To calculate the number of moles in 150 grams of NaCl, you need to know the molar mass of NaCl, which is approximately 58.44 g/mol. You can then divide the given mass (150 grams) by the molar mass to get the number of moles. In this case, 150 g / 58.44 g/mol ≈ 2.57 moles of NaCl.
To find the number of moles in 234g of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is 58.44 g/mol (sodium = 22.99 g/mol, chlorine = 35.45 g/mol). So, 234g ÷ 58.44 g/mol = 4 moles of NaCl.
To determine the number of moles in 50g of NaCl, you first need to find the molar mass of NaCl, which is approximately 58.44 g/mol. Then, you divide the given mass by the molar mass to find the number of moles. So, 50g of NaCl represents approximately 0.855 moles (50g / 58.44 g/mol = 0.855 mol).
