A. Oxygen-18 is the correct reference for this isotope. As this notation requires the name of the element followed by a dash and the mass number of that corresponding element. The mass number is obtained by adding the number of protons and neutrons together as in this example.
Answer:
178 torr
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 5 mL
V₂ = 5 mL (Closed container)
P₁ = 95.0 torr
P₂ = ?
T₁ = 28.0 ºC
T₂ = 290 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (28 + 273.15) K = 301.15 K
T₂ = (290 + 273.15) K = 563.15 K
Using above equation as:
Solving for V₂ , we get:
P₂ = 178 torr
