Answer:
21.3dm³
Explanation:
Given parameters:
Initial volume of gas = 3dm³
Initial pressure = 101kPa
Final pressure = 14.2kPa
Unknown
Final volume = ?
Solution:
To solve this problem, we use the Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁ V₁ = P₂ V₂
P and V are pressure and Volume
1 and 2 are the initial and final states
Now insert the parameters and solve;
101 x 3 = 14.2 x V₂
V₂ = 21.3dm³
To contain the same number of atoms also mean to contain
the same number of moles. So let us say that X is the mass of Silver Ag
required, so that:
X / 107.87 = 10 / 10.81
<span>X = 99.79 g</span>
From high pressure to lower pressure.
