What is the activity coefficient of H in a solution containing 0.073 M HCl and 0.0090 M Ca(ClO4)2? A table of activity coefficients at various ionic strengths can be found here. What is the pH of the solution?

The value is

Explanation:

From the question we are told that

The concentration of is

The concentration of is

The concentration of is

The concentration of is

Generally the log of the activity coefficient is mathematically represented as

Here z is the charge which for is +1

is the size which for is

is the ionic strength which is mathematically represented as

=>

So

=>

=>

=>

Generally the pH is mathematically represented as

=>

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
