Be sure to answer all parts.

Report your answer with the proper number of significant figures. Magnesium is used in lightweight alloys for airplane bodies and other structures. The metal is obtained from seawater in a process that includes precipitation, neutralization, evaporation, and electrolysis. How many kilograms of magnesium can be obtained from 7.00 km3 of seawater if the initial Mg2+concentration is

0.15%

by mass?

(d of seawater = 1.04 g/mL)

I got 1.06 x 10^14 not right

Answer #1

7 tam3 = 7x10 15m L. Mom of 7x10* mL seawater = 1.048 x 7x10 L Amount of 27.28 X10 Mg2@ in 7:28 X101 a 10 g = 7:28 X10159

Hence, 1.092 x 1010 kg of Mg2+ can be obtained from 7 kg3 of seawater in the mentioned Mg2+ concentration.
