<u>Answer:</u> The concentration of KOH solution is 1.215 M
<u>Explanation:</u>
For the given chemical equation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is KOH.
We are given:
Putting values in above equation, we get:
Hence, the concentration of KOH solution is 1.215 M
Answer:just right this->”150 words”and bammm your done
Explanation:I mean they said right 150 words
Answer:
C. molecules
Explanation:
Since, the temperature, pressure and volume conditions are same, the molecules of ammonia gas must be equal to the molecules of the argon according to the ideal gas equation which is shown below as:-
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Thus, both will have same moles and same number of molecules.
<u>Thus, molecules of argon = molecules</u>
Endothermic bc of the temperature change
