Two buckets of seawater contain $13\frac{28}{40}$ kg of salt.

Step-by-step explanation:

Amount of salt in 1 kg water = $\frac{1}{40}\ kg$

It is given that;

1 liter = $1\frac{12}{125} = \frac{137}{125}\ kg$

500 liters = $500*\frac{137}{125} = \frac{68500}{125}$

500 liters = 548 kilogram

As,

1 kg of seawater = $\frac{1}{40}\ kg$ of salt

548 kilograms = $\frac{1}{40}*548$

548 kilograms = $13\frac{28}{40}$ kilograms of salt

Two buckets of seawater contain $13\frac{28}{40}$ kg of salt.
