You create a solution for a lab, in which you weigh 0. 81 g of nacl and dissolve it in water. The volume of the resulting aqueous nacl solution is 12. 2 ml. Assuming the molar mass of nacl is 58. 443 g/mol, how many moles of nacl did you use?.

Answer :

This volume will therefore be X. X is equivalent to 1.369 divided by 1, or 0.1. Thus, this is equivalent to run 369 and almost 14 liters.

At 80 degrees Celsius, 40 grams of sodium chloride are soluble in 100 grams of water. The mass of the solvent and the mass of the solute together make up the total mass of the solution. Use a lab scale to weigh the masses or use the density formula D = m/V to convert the solvent volume to mass. To determine your final volume, multiply the mass of the solvent by the mass of the solute. A 10% solution of NaCl is 10 grams of NaCl in 100 ml of water because in this situation, the% solution is the number of grams of solute in 100 ml of solvent.
