Answer:
(215 torr)(51 mL)=("x" torr)(18,500 mL) x = O.593 torr
Answer:
4.87 g
Explanation:
The formula between the number of moles, mass and Mr can be used to find the mass of barium.
<em>Number of moles = mass ÷ Mr</em>
So, mass = number of moles × Mr
Mr of Ba = 137.3
∴ Mass = (3.55 × 10⁻²) × 137.3 = 4.87 g
Answer:
449 mL
Explanation:
Using Ideal gas equation for same mole of gas as
Given ,
V₁ = 450 mL
V₂ = ?
P₁ = 101 kPa
P₂ = 104 kPa
T₁ = 17 ºC
T₂ = 25 ºC
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (17 + 273.15) K = 290.15 K
T₂ = (25 + 273.15) K = 298.15 K
Using above equation as:
Solving for V₂ , we get:
V₂ = 449 mL
