Question
10. 500g of AlbSa is dissolved in H20 to make 15.0 L of solution. What is its normality? (MW: Al-27g/mol, S=32g/mol, H=1g/mol, 0-16g/mol) A. 0.11 N B. 0.07 N C. 0.22 N D. 0.04 N 11. The concentration of a 1500mL aqueous KCI solution was increased from 25.0 M to 80.0 M by evaporation. How much H20 was removed? (MW: K=39g/mol, CI=35g/mol, H-1g/mol, 0=16g/mol) A. 1.03 L B. 0.47 L C. 1968.75 ml D. 4.68.75 ml 12. Suppose that 15M of NaCl solution with a volume of 15L is heated and loses 2000ml of its water content. What would be the final concentration of your NaCi sample? (MW: Na=23g/mol, Cl=35g/mol, H=1g/mol, 0=16g/mol) A. 3.75 M B. 0.0375 M C. 37.5 M D. 375.0 M 13. How much ml of ethanol is needed to make 2000ml of an aqueous 15% (v/v) solution? A. 3000 ml B. 300 ml C. 30 ml D. None of the above
