Answer:
V₂ = 150 mL
Explanation:
Given data:
Initial volume of sample = 250 mL
Initial pressure = 450 mmHg (450 /760 = 0.6 atm)
Final pressure = standard = 1 atm
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
0.6 atm × 250 mL = 1 atm × V₂
150 atm. mL = 1 atm × V₂
V₂ = 150 atm. mL/ 1 atm
V₂ = 150 mL
Answer:
Four
Explanation:
The electron dot diagram of elements or ions depict only the valence electrons. Carbon has atomic number of 6. The first shell has 2 electrons and gets filled. The second shell is filled by the remaining four electrons.The 4 electrons of the valence shell is shown in the electron dot diagram.
