Question
1) Seawater contains 8.0 x 10-1 cg of the elementstrontium per kg of seawater. Assuming all of the strontium couldbe recovered, how many grams of strontium can be recovered from acubic meter of seawater? Assume the density of seawater is 1.00g/mL. I would like to see all the steps, please. 2) There are 6.02 x 1023atoms of mercury in 201grams of mercury. The density of mercury is 13.5 g/mL. What is thevolume in m3, occupied by one mercury atom? I would like to see all the steps please. 1) Seawater contains 8.0 x 10-1 cg of the elementstrontium per kg of seawater.

1m3*(10dm/1m)3*(1L/1dm3)*(1000mL/1L)*(1g seawater/1mL)* (1kg/1000g)*(8.0 e-1 cg strontium/kg seawater)*(1g/100cg) = 8 grams of Strontium 2) (201g/6.022e23atoms)*(1mL/13.5g)*(1L/1000mL)*(1dm3/1L)*(1e6um/1dm)^3 = 2.47 x 10-11 um3
