Answer:
55 protons, 78 neutrons, 55 electrons
Explanation:
In a neutral Cesium atom we have 55 protons, 78 neutrons and 55 electrons. This can be found on the periodic table of elements.
Protons are the positively charged particles within an atom
Neutrons do not carry any charges.
Electrons are the negatively charged particles.
The amount of these subatomic particles can be obtained from the periodic table of element.
For a neutral atom, the number of protons and electrons are the same.
Since the atomic number is 55, it is also the number of protons in the atom.
Answer:
a
Explanation:
Because the mass would stay the same and the flavor did not change and neither did the color so the shape is the only thing that changed
Volume of room = 
= 
Now, according to conversion factor, convert 6,400 mg to micrograms
Since, 1 mg is equal to 1000 microgram.
Therefore, 6,400 mg = 
= 6,400,000 micrograms of acetone.
To calculate concentration of acetone, divide volume and evaporated amount of acetone in micrograms.
Thus,
Concentration of acetone = 
= 39296.5910 microgram per cubic meter or 
Hence, concentration of acetone is equal to
