Erin must perform a science experiment. She needs to dissolve 10 g of salt in 250 ml of water. She measures the water incorrectly and dissolves the 10 g of salt in 350 ml of water. Now she has no more salt. Explain what Erin can do to make the solution accurate.

  • science -

    She could add more salt.

    Solve this proportion to find how much salt is needed in 350 ml.

    250 / 350 = 10 / x

  • science -

    She can't add more salt because she has no more salt.

  • science -

    Oops! Sorry. I didn't read the entire question.

    The only other solution I see is to let the excess water evaporate.

  • science -

    So if she lets the water evaporate, she can use the remaining salt to use it in another cip with 250 ml of water

  • science -

    She only needs to let the excess water (100 ml) evaporate.

  • science -

    How can she make sure its 100 ml?

  • science -

    She can note the amount of salt and water in a flask marked in ml.
