The sea water has 8.0x10^-1 cg of element strontium. Assuming that all strontium could be recovered, how many grams of strontium could be obtained from 9.84x10^8 cubic meter of seawater. Assuming the density of sea water is 1.0g/mL.

984 grams of strontium will be recovered from 9.84x10^8 cubic meter of seawater.

Explanation:

From the question data given is :

volume of strontium in sea water= 9.84x10^8 cubic meter

(1 cubic metre = 1000000 ml)

so 9 .84x10^8 cubic meter

       = 984 ml.

density of sea water = 1 gram/ml

from the formula mass of strontium can be calculated.

density =

mass = density x volume

mass = 1 x 984

         = 984 grams of strontium will be recovered.

98400 centigram of strontium will be recovered.

Strontium is an alkaline earth metal and is highly reactive.

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
