Answer:
V₂ = 46.34 mL
Explanation:
Given data:
Initial temperature = 273 K
Initial volume = 50.0 mL
Final temperature = 253 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
Charles Law
"The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure"
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
by putting values in formula,
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 50.0 mL × 253 K / 273 k
V₂ = 12650 mL.K / 273 K
V₂ = 46.34mL
Answer:
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
