Answer:
Relative atomic mass and it is expressed in atomic mass unit (amu)
Explanation:
AMU:
Atomic mass unit is define as the 1/12 the mass of an atom of carbon-12.
C12 has six neutron and six protons in the nucleus.
This unit is used to express the masses of atoms. We know that masses of atoms are very small and we do not have any such type of balance that can measure very small quantity. So that is way we use this scale to measure small quantity. For example, according to this scale
relative atomic mass of hydrogen is 1.008 amu
relative atomic mass of oxygen is 15.999 amu
relative atomic mass of uranium is 238.0289 amu
relative atomic mass of chlorine is 35.453 amu

Explanation:
Let us assume that volumes is equal to spheres volume of nucleus.
fm = femto meter = 
pm = pico meter = 
Hence, calculate the volume as follows.
V = 
= 
= 82.4481 
(cubic femtometers)
or, = 82
Now, we will calculate the volume of the atom as follows.
V =
= 
= 1436758.4 
(cubic picometers)
thus, we can conclude that volume of the nucleus is 82 and volume of the atom is 1436758.4 .
The answer is D because most stained glass is held together with lead. The process of this is called leading.
Answer:
Laura can look for a transparent and translucent liquid and hence determine which beaker has water and which has solution
Explanation:
Pure water is a compound that is transparent in color. However, a solution is a liquid mixture comprising of a solvent or a solute. The atoms of solute occupy space between the atoms of solvent and hence are said to dissolve in it. Water can be a solvent.
Thus, if the beaker has a transparent liquid in it, then it would be pure water while a beaker having a translucent liquid, then it would be a solution
