...."heavier". *The definition of radioactive decay shall do its explanation.
<u>Answer:</u>
concentration of H ions = 0.0001 M
<u>Explanation:</u>
Base 10 logarithm of the H+ concentration when multiplied by -1 is equal to the pH value of a solution. By reversing this formula, we can find the concentration of the H+ in the solution:
pH = ㏒
or = concentration of H+
We know that, pH of the solution is 4.0,
so =
Therefore, the concentration of Hydrogen ions in a solution of pH = 4 is 0.0001 M.
The ideal gas law may be written as
where
p = pressure
ρ =density
T = temperature
M = molar mass
R = 8.314 J/(mol-K)
For the given problem,
ρ = 0.09 g/L = 0.09 kg/m³
T = 26°C = 26+273 K = 299 K
M = 1.008 g/mol = 1.008 x 10⁻³ kg/mol
Therefore
Note that 1 atm = 101325 Pa
Therefore
p = 2.2195 x 10⁵ Pa
= 221.95 kPa
= (2.295 x 10⁵)/101325 atm
= 2.19 atm
Answer:
2.2195 x 10⁵ Pa (or 221.95 kPa or 2.19 atm)
