How to separate salt and sand from water and calculate the percent of mass?

Answer 1

You add water to the container then you stir, the water and salt would form a solution and sand would settle on the bottom of the container. You get another container and place on a filter paper then you pour the water into it, which would lead to the sand staying in the filter paper and the solution, which is made of salt and water, would be left. Finally, you place the container on a source of heat which will cause the water to evaporate and salt staying in the container.

Now weigh the residue and find the percentage.

Answer 2

To separate salt from sand in water, you can use the process of filtration to separate the salt and sand mixture from the water. Then, you can evaporate the water to leave the salt behind. To calculate the percent mass of salt in the mixture, divide the mass of salt by the total mass of the mixture (salt + sand) and multiply by 100.
