You may suppose you have a 0.1 M solution of NH3, from:

NH4Cl + NaOH > NH3 + H2O.

Then you can compute the pH from the concentration of NH3 and its pKb.

The concentration is high enough to use the simplified formula:

[OH] = sqr(Kb*conc)

If the volume occupied by the gas molecules shown below were doubled, what would happen to the pressure they exert? (Assume cons
AnnZ [28]

there's no picture here but I guess the answer would be:

considering the constant temperature, if you double the volume, the pressure would be halved.

like: volume is 2, pressure is 4

if 2×2, then:4÷2
