The solubility product of barium sulphate is 1.21 xx 10^(-11) at 25^@C . Calculate its solubility in kgdm^-3 at the same temperature.

Calculate the pH of 2.5 xx 10^(-4) M HCl solution.

A certain particle carries 2.5 xx 10^-16C of static electric charge. Calculate the number of electrons present in it.

The compressive ratio of a certain diesel engine is 15 . This means that air in the cylinder is compressed to 1/15 of its initial volume. If the initial pressure is 1.0 xx10^5 Pa and the initial temperature is 300 K, find the final pressure and temperature after compression. Air is mostly a mixture of oxygen and nitrogen and y = 1.4
