i. Obtain three beakers, one container of salt, one triple beam balance, and

one graduated cylinder. Label the beakers A, B, and C.

ii. Dry the first beaker and take its mass. Record the mass of the beaker in

the data table located in the data section of this lab.

iii. On the data table, add the numbers from the columns “Mass of Salt” and

“Mass of Beaker” for the desired solution and write the answer in the

column “Mass of Salt and Beaker.” This calculated mass is the mass you

wish to obtain when you add the salt.
