Answer:
Explanation:
Graham’s Law applies to the diffusion of gases:
The rate of diffusion (r) of a gas is inversely proportional to the square root of its molar mass (M).
If you have two gases, the ratio of their rates of diffusion is
The time for diffusion is inversely proportional to the rate.
Data:
t₂ = 222 s
t₁ = 175 s
M₁ = 28.01
Calculation
:
A gas is something that takes up the space of the container, because it doesn't have a fixed shape.
Explanation:
density(d) = mass(m) × volume(v)
given:
mass = 4.3 g = 0.0043 Kg
volume = 2.7 cm³ = 0.027 m³
= 0.0043 Kg / 0.0027 m³
= 0.15 Kg/m³
