The first step we have to follow is to convert the given tons to grams:

$8.0*10^4tons\cdot\frac{1000\operatorname{kg}}{1ton}\cdot\frac{1000g}{1\operatorname{kg}}=8*10^(10)g$

Use the given ratio of grams of Mg to kg of seawater to find how much of seawater is needed:

$8*10^(10)gMg\cdot(1kgseawater)/(1.3gMg)=6.15*10^(10)kgseawater$

Use the density of seawater to find how many liters are needed:

$6.15*10^(10)\operatorname{kg}\cdot\frac{1000g}{1\operatorname{kg}}\cdot(1ml)/(1.03g)\cdot(1l)/(1000ml)=5.97*10^(10)l$

5.97x10^10 liters are needed to extract that amount of Mg.
