Aclosed flask of air (0.250 l) contains 5.00 "puffs" of particles. the pressure probe on the flask reads 93 kpa. a student uses a syringe to add an additional 3.00 "puffs" of air through the stopper. find a new pressure inside the flask.

New pressure inside the flask would be 148.8 kPa.

Explanation: The combined gas law equation is given by:

As the flask is a closed flask, so the volume remains constant. Temperature is constant also.

So, the relation between pressure and number of moles becomes

Putting the values, in above equation, we get

since electrons are negative the answer is neagtaive
