Ammonia (NH3) is the active cleaning ingredient in Windex and is also the main contributor to the odor of stale cat urine. Ammonia has a ΔH°vap of 23.35 kJ/mol and a ΔS°vap of 97.43 J/mol·K. What is the normal boiling point of ammonia

Explanation:

Hello!

In this case, since the relationship between entropy and enthalpy for any process is defined below:

For the vaporization of ammonia or any liquid, we can write:

In such a way, solving the temperature of vaporization, or boiling point, we have:

Plugging in the given enthalpy and entropy of vaporization we obtain:

Best regards!

i believe the answer is a.

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
