P V = n R T
You have three times as many molecules or mols
new n = 3 * original n
V, R and T the same
so new P = 3*old P
Please help!
N2H4 is decomposed in a closed container according to this reaction: N2H4 → N2 + 2H2 . If the temperature is constant and the initial pressure of N2H4 is 800mm, what will the pressure in millimeters be after the decomposition to N2 + 2H2?
