Answer:
Double-Replacement Reactions
Explanation:
KOH + HNO3 -> H2O + KNO3
This is a double replacement reaction
The anions are "traded" and two new compounds are produced
(a liquid and a salt)
Using ideal gas equation, PV = nRT, and since there is no volume change and amount change, the equation is now P = kT, where k =nR/V. Temperature must be in kelvin
From the given, k = (0.82)/ (21 + 273) = 2.78 x 10^-3
Substituting T = -3.5+273, P = 0.75 atm
Answer: 2.62 x 10^22 atoms
