Describe how to prepare 100.00ml of a 0.250M sodium chloride solution using sodium chloride powder.

This question is part two of three. When answering this problem, report the answer with the appropriate number of significant figures. When entering units, use proper abbreviated units with proper capitalization. A solution is prepared by combining 5.92 grams of an unknown non-electrolyte with 240.0 grams of chloroform. The freezing point of the mixture is -64.80 oC, while the freezing point of pure chloroform is -63.50oC. The kf of pure chloroform is 4.68oC/molal. Based on this information, how many moles of solute are present in this solution? What is the molar mass of the solute?  Report both answers in scientific notation with appropriate sig figs.

If you were to prepare 100mL of a 0.26M solution of Benzocaine, determine the mass of benzocaine required.

34.1 % (NH4 )2SO4   (molar mass = 132.1 g mol−1) has a density of 1.15 g mL−1. What is the molarity of this solution?  (the answer should be entered with 3 significant figures; do not enter units; give answer in normal notation--examples include 1.23 and 120. and -123 and 123. and 12.3)     Determine the boiling point of a solution that contains 78.5 g of compound W (molar mass = 132.5 g mol–1) dissolved in 1088.6 g benzene (C6H6; molar mass = 84.156 g mol–1; Kb = 2.53 °C m–1; boiling point of pure benzene = 80.1 °C). (the answer should be entered with 3 significant figures; do not enter units; give answer in normal notation--examples include 1.23 and 120. and -123 and 123. and 12.3)
