Answer: 
Explanation:
Required amount of magnesium = 
Given : 1 ton = 2000 lb

1 lb = 453.592 g

Given : 1.4 g of magnesium is produced by 1000 g of sea water
of magnesium is produced by =
g of sea water
Density of sea water = 1.025 g/ml
Volume of sea water =
1 ml = 

Volume of seawater, in cubic meters is 
<span>175.5g
</span>Cl(35.5) x 3 = 106.5
Na(23) x 3 = 69
106.5 + 69 = 175.5g
or
0g because sodium and chlorine are not chemically bonded.
