The existing 4mol / L NaCl solution is 100ml, and the molar mass of sodium chloride is? Mass is?

58.5 g / mol, 0.4 * 58.5

What are the mass solubility and molar solubility of 2.9g NaCl in 2kg water?

1. Mass concentration = solute mass / solution mass = 2.9 / (2000 + 2.9) * 100% = 0.145% 2 molal solubility, because the amount of NaCl is 2.9 / 58.5 = 0.05 mol. because the content of solute NaCl is very small, the density of solution is approximately 1 g / ml, so the volume of solution is 2 l molal concentration
