79,200 feet.
Just multiply the total miles times the amount of feet in a single mile.
15 X 5280 ft= 79,200 feet
Answer:
The answer to your question is Volume = 0.12 L
Explanation:
- Data
Pressure 1 = 1 atm
Volume 1 = 1.82 L
Pressure 2 = 15 atm
Volume 2 = ?
Temperature = constant
- Formula
- To solve this problem use the Boyle's law
P1V1 = P2V2
- Solve for V2
V2 = P1V1 / P2
- Substitution
V2 = (1)(1.82) / 15
- Simplification
V2 = 1.82 / 15
- Result
V2 = 0.12 L
To do this, we need molar mass, as well as Avogadro's Number.
To start, 1.60 x 10-12 grams C10H16O. Molar mass = 152.23 g/mol
Divide 1.60 x 10-12 grams by 152.23 g/mol to get a number in moles.
You should get 1.05 x 10-14 moles
From here, we use Avogadro's Numner, 6.022 x 10^23 molecules/mole.
Multiply our moles, 1.05 x 10-14 by 6.022 x 10^23
Answer:
6.33 x 10^9 molecules.

Answer:
Phosphorus
Explanation:
Lewis Dot Structure is a structural representation of a molecule that shows valence electrons of a molecule.
The element in group 15, period 3 is Phosphorus (P). Phosphorus has an atomic number 15 and valence electrons are 5. So, the lewis structure will show 5 dots around P atom.
I think the correct answer from the choices listed above is option A. In the modern periodic table, elements are arranged according to increasing <span>atomic number. The atomic number represents the number of protons present for a specific atom.</span>
