Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jack is stranded on a desert island. He wants some salt to season his fish. He collects 2 liters of seawater in an old bucket. If the water is 20% salt, how many ml of salt will Jack get when all the water evaporates?

### Response:
 Kwanza, tafuta ni lita ngapi za maji ya bahari ni chumvi: 2 lita * 20% = <<2*20*.01=.4>>.4 lita
Kisha, zidisha idadi hiyo na 1000 ml/lita ili kupata idadi ya mililita ya chumvi ambayo Jack atapata: .4 lita * 1000 ml/lita = <<.4*1000=400>>400 ml
