Question

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.

Answer 1

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

Step-by-step 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

`(9 .84x10^8)/(1000000)` = 984 ml.

density of sea water = 1 gram/ml

from the formula mass of strontium can be calculated.

density =
`(mass)/(volume)`

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.
