1) The Seawater having the 8.0 x 10-1 cg of the element strontium per kg of seawater. Suppose all of the strontium could be recovered, determine the number of grams of strontium can be improved from a cubic meter of seawater? Let the density of seawater is 1.00g/mL.
2) There are 6.02 x 1023atoms of mercury in 201grams of mercury. Let the density of mercury is 13.5 g/mL. Determine the volume in μm3, which is occupied by one mercury atom?
