Answer : The concentration of NaOH is, 0.336 M
Explanation:
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 NaOH.
We are given:
Putting values in above equation, we get:
Thus, the concentration of NaOH is, 0.336 M
Answer:
Ionic Compounds have high boiling and melting points as they're very strong and require a lot of energy to break. The electrostatic forces of attraction between oppositely charged ions lead to the formation of ions. Ionic compounds form crystals. These compounds are brittle and break into small pieces easily.
Explanation:
Answer:
1.62 L
Explanation:
T= 97+273.15= 370.15
R= 0.08206 atm/mol⋅K
V= 45 L
n= 2.4 mol
P= (n⋅R⋅T)/V
= (2.4 x 0.08206 x 370.15)/(45) = 1.61997 = 1.62
