How can you separate sand and water without filter paper

Liula [17]

Answer:

through Decantation

Explanation:

Decantation: Decantation is pouring out of upper clear layer of liquid into another container to separate two immiscible liquids or to separate different substances in a suspension mixture.

Therefore, we could use decantation once the sand particles settle down by gently pouring the water into another container. Once the water is transfered, we'll be left with sand in the bottom of the first container.

Hope that helps...

3.2 g / 4 L = 8 g / x L

The value of x from the equation is 10.
