hypothesis : Regardless of symmetry of a pure solid substance, the density determined should be the same. 1. Are the results are reasonable? When discussing the density of anything it did not matter how much of the substance there wa always the same. So the density of brass was 8.73 g/cm^3, for the scale density is 8.658 g/cm^ g/cm^3 for the digitial density . Then the density for the alumium is 2.7g/cm^3, for the scale de g/cm^3, and 2.275 g/cm^3 for the digital density. wwhen lookingat the results they are reasona natural. 2. List all the errors and ways to minimize them. We had systematric error with our measurments. With the meter stick there was uncertainty be not get an exact measurement. In addition wwith the scale we between numbers possibly beca calabriating before hand. Nextime we need to calbrate the. scale and try to determine more of measurement mayne by using a different type of rule. For example a milimeter stick and conver

d by experiment as the deinsity was ^3, and 8.46 ensity is 2.76 able and similar in ecause we could ause of lack of an exact rt to meter.
