Homework Help: Best way to determine the weight/volume of a grain of sand/salt

  1. Sep 10, 2005 #1
    I'm not looking into anyone giving me any answers here, but I just want to gather some ideas for a lab that requires me to calculate the volume and wieght (therefore, finding the density) of a grain of salt and sand.

    I've thought about the idea of counting out 100 grains and then weighing them, then dividing it by 100 for weight. And to use a water displacement method to find the volume, again using 100 grains of salt.

    Does anyone have any other possible ideas?

    Any advice, input, and thoughts, would we well recieved.



    P.S. - My teacher says that is a lab that will not work effectively. The teacher is more interested in finding out how I do the lab, not my lab results.

    Your method sounds like the way most people would do it.
