We can use the ideal gas law equation to find the volume of the gas.
PV = nRT
P - pressure - 400 kPa
V - volume
n - number of moles - 4.00 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - 300.0 K
substituting these values in the equation
400 000 Pa x V = 4.00 mol x 8.314 Jmol⁻¹K⁻¹ x 300.0 K
V = 24.9 dm³
Volume is 24.9 dm³

<u><em>Answer:</em></u>The compound ammonia given by fish is alkaline
<u><em>Explanation:</em></u><u>We can classify elements/compounds based on their pH values into three types:</u>
<u>acids:</u> these are compounds having pH value lower than 7
<u>neutral:</u> these are compounds having pH value equal to 7
<u>alkalies:</u> these are compounds having pH values higher than 7
This is shown in the attached image
We are given that the pH of the compound ammonia generated by the fish is
above 7.
According to the above explanation, compound ammonia would be an alkaline compound.
Hope this helps :)</span>
