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.

How many moles are in 8.4 x 1023 formula units NaCl?
To find the number of moles in 8.4 x 10^23 formula units of NaCl, you need to convert formula units to moles. Since 1 mole of any substance contains Avogadro's number of particles (6.022 x 10^23), you would divide the number of formula units by Avogadro's number to get the answer. So, 8.4 x 10^23 formula units of NaCl is equal to 1.4 moles of NaCl.

What would you need to do to calculate the molality of 10 g of NaCI in 2kg of water?
To calculate the molality of NaCl in water, first, you need to determine the number of moles of NaCl by using its molar mass (approximately 58.44 g/mol). For 10 g of NaCl, divide 10 g by 58.44 g/mol to find the moles. Then, use the mass of the solvent (water) in kilograms; since you have 2 kg of water, molality is calculated as the number of moles of solute divided by the mass of solvent in kilograms. The formula is: molality (m) = moles of solute / kg of solvent.

What would you be need to do to calculate the molarity of 10 mol of NaCl in 200?
To calculate the molarity of a solution, you would need to divide the number of moles of solute (in this case, 10 mol of NaCl) by the volume of solution in liters (in this case, 200 L). Molarity = moles of solute / liters of solution So, Molarity = 10 mol / 200 L = 0.05 M.

What would you need to calculate the molality of 10 g of NaCI in 2 kg of water?
To calculate the molality of 10 g of NaCl in 2 kg of water, you need to determine the number of moles of NaCl and the mass of the solvent (water) in kilograms. First, calculate the molar mass of NaCl, which is approximately 58.44 g/mol. Then, divide the mass of NaCl (10 g) by its molar mass to find the number of moles, and finally, use the formula for molality: molality = moles of solute / mass of solvent (in kg). In this case, the calculation would be molality = (10 g / 58.44 g/mol) / 2 kg.
