The answer is (2) 2. First of all, a greater hydronium ion concentration means more acidic, so we need a lower pH. Also, you need to remember that pH is on a base 10 log scale. This means that a difference by a factor of 10 in concentration is a difference of 1 on the pH scale. So since the difference is a factor of 100 (10^2), the difference is 2. We already established that the pH must be lower, so your answer is 4 - 2 = 2.
Ideal gas law is a combination of three gas laws, which are Boyle's law, Charles' law and Avogadro's law. Ideal gas law states that PV = nRT, where:
P = pressure of the gas
V = volume of the gas
n = no of moles of the gas
R = universal gas constant
T = absolute temperature in Kelvin
Moles = Mass/Molar Mass
By this formula 458/207+32 you should get your answer.
Answer is 1.916 mol to 4 sig. Fig.
