1. Ten grams of plastic beads with a density of 1.2g/cm^3 are added to 500mL of an organic solvent with a density of 0.80g/cm^3. What is the concentration of plastic beads in mg/L?

         

The concentration of Mg2+ in a sample of coastal seawater is 1.09 g/kg. What is the molar concentration of Mg2+ in water with a density of 1.02 g/mL?

1/ if an organic liquid with a density of 0.7 g/ml was added to a separatory funnel with water, would the liquid be found on top or below the aqueous layer?why?

2/ if an organic liquid with a density of 1.4 g/ml was added to a separatory funnel with water, would the liquid be found on top or below the aqueous layer?why?

3/ if adipic acid was dissolved in an organic solvent, could it be extracted into an aqueous layer with the addition of sodium hydroxide?
