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

### Instruction:
Dana normally drinks a 500 ml bottle of soda each day. Since the 500 ml bottles are currently out of stock at the store, she buys a 2-liter bottle of soda instead. If Dana continues to drink 500 ml of soda each day, how long will the 2-liter bottle of soda last? There are 1,000 ml in 1 liter.

### Response:
 ขวดน้ำอัดลมขนาด 2 ลิตรมี 2*1,000 มล. = <<2*1000=2000>>2,000 มล.
ขวดน้ำอัดลมขนาด 2 ลิตรจะอยู่ได้ 2,000/500 = <<2000/500=4>>4 วัน.
