Two moles of sodium chloride is equivalent to 116,88 (rounded) g.
The molar mass of NaCl 58.5 grams per mole. 117 grams of salt is equivalent to two moles. Dissolve this much of salt in exactly 1L of distilled water in a volumetric flask to prepare 2M NaCl.
Need moles NaCl first. 17.52 grams NaCl (1 mole NaCl/58.44 grams) = 0.29979 moles NaCl =====================Now. Molarity = moles of solute/Liters of solution ( 2000 ml = 2 Liters ) Molarity = 0.29979 mole NaCl/2 Liters = 0.1499 M NaCl ----------------------
Molarity = moles of solute/Liters of solution Molarity = 6 Moles NaCl/2 Liters = 3 M NaCl ========
To make 1 liter of 0.4 M NaCl solution, you would need 200 mL of 2 M NaCl solution. This can be calculated using the formula Mi x Vi = Mf x Vf, where Mi is the initial molarity, Vi is the initial volume, Mf is the final molarity, and Vf is the final volume.
This molarity is 3 M.
The molar mass of sodium chloride (NaCl) is 58.44 g/mol. First, calculate the number of moles of NaCl in 117 grams: 117 g / 58.44 g/mol = 2 moles. Next, calculate the molarity: 2 moles / 40.0 L = 0.05 M. Hence, the molarity of the solution is 0.05 M.
6mol/2L
Molarity is defined as moles solute/liter of solution6 moles/2 liters solution = 3 molar NOTE: This assumes no volume change and 2L is the final volume of solution.
concentration or molarity = number of moles/volume number of moles (n) = mass in grams of nacl/relative atomic mass of nacl n=17.52/(23+35.5) n = 0.2994872 mol volume = 2000/1000 = 2dm^3 molarity = 0.2994872/2 =0.15mol/dm^3
Molarity = moles of solute/volume of solution Find moles NaCl 55 grams NaCl (1mol NaCl/58.44 grams) = 0.941 moles NaCl Molarity = 0.941 moles NaCl/35 Liters = 0.027 Molarity NaCl ( sounds reasonable as 55 grams is not much in 35 Liters of water, which would be about 17.5 2 liter sodas )
The molarity of the solution is 3 M. This is calculated by dividing the moles of solute by the volume of solution in liters. In this case, 6 moles divided by 2 liters equals a molarity of 3 M.
To calculate the molarity of a substance, you need to know the moles of the substance and the volume of the solution. First, convert the mass of NaCl to moles, then calculate the total volume of the solution. Finally, divide the moles of NaCl by the volume of the solution in liters to get the molarity.
To calculate the molarity of 10 g of NaCl in 2 kg of water, you would first need to convert the mass of NaCl to moles using its molar mass. Then, calculate the total volume of the solution by considering the density of water (1 kg = 1 L). Finally, divide the moles of NaCl by the volume of the solution in liters to determine the molarity.
