Agas sample has an initial volume of 63.2 ml, an initial temperature of 42.0 ? c, and an initial pressure of 751 mmhg. the volume is decreased to 47.6 ml and the temperature is increased to 77.0 ? c.

Lets Write Down the Given Initial Conditions.

In Order to Solve for the Unknown:

we must use the Ideal Gas Law to Solve for the Second Unknown pressure:

Then Rearrange this equation in a form where P2 can be solved from:

Then Insert the Values from above to solve:

The Answer is : 1830 mmHg considering sig figs

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

i think its 100.

hope this !
