Elizabeth is testing the effects of soil additives on fruit production at an apple orchard. elizabeth would like to find out if the soil additives increase the mass of the apples. what tool will elizabeth need in order to complete her research? a. graduated cylinder b. beaker c. balance d. ph meter

The correct answer is option C. balance.

The balance can be used to calculate the mass of apple. In this case, she need to take a normal apple, which grow in untreated soil and one apple, which grow in treated soil, she should make sure, the apples are of similar size and shape. by using balance she can measure the mass of apple and determine the difference between masses of two apples.

The graduated cylinder is used to detect change in volume, so it is not useful.

The beaker is used to hold liquids, it cannot measure anything, so it is also not useful.

The pH meter determine pH of the substance, hence, it is also not useful.

it is prolly d and c and f

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
