Q1. If there were some dirt on your 50 mL beaker that was not removed before you began the experiment, it is important to understand how it would affect your mass measurements and your density
result. Would the masses be high, low or unchanged by the dirt? Would the density be high, low or
unchanged by the dirt? Explain your answer.

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
