Explanation:
The answer is very probable because of how incredibly small atoms are
Very probable because of how incredibly small atoms are the chances that at least one of the atoms exhaled in your first breath will be in your last breath.
Hydrogen and oxygen always react in a 1:8 ratio by mass to form water. early investigators thought this meant that oxygen was 8 times more massive than hydrogen.
If you say that something is probable, you mean that it is likely to be true or likely to happen.
Everything around us is made up of really tiny molecules. However, such molecules are constructed from much smaller atoms. Then, even smaller protons, neutrons, and electrons are used to build those atoms. Quarks, which are even smaller particles than protons, make up protons.
The smallest unit of substance that may be disassembled without ejecting any electrically charged particles is the atom. The smallest piece of substance that displays an element's distinctive qualities is an atom. As a result, the atom serves as the basic unit of chemistry.

Answer:
34.6 cm³
Explanation:
<em>A chemistry student needs 55.0 g of carbon tetrachloride for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of carbon tetrachloride is 1.59 g/cm³. Calculate the volume of carbon tetrachloride the student should pour out. Be sure your answer has the correct number of significant digits.</em>
Step 1: Given data
- Mass of carbon tetrachloride (m): 55.0 g
- Density of carbon tetrachloride (ρ): 1.59 g/cm³
Step 2: Calculate the required volume of carbon tetrachloride
Density is an intrinsic property of matter. It can be calculated as the quotient between the mass of the sample and its volume.
ρ = m/V
V = m/ρ
V = 55.0 g/(1.59 g/cm³)
V = 34.6 cm³
The chemistry student should pour 34.6 cm³ of carbon tetrachloride.
