Problem-Solving Strategies: Guide to Using the Gas Laws 20 of 33 Part C-Practice the steps for a multi-step problem Sometimes the problem will give the initial and final states in different units. In this case, you need to identify all of the pressures and all of the volumes by organizing them into a table (step 1 of our problem solving method). Then, you need to convert all of your pressures to the same units (usually atmospheres works best) and all of your volumes to the same units (usually liters). Then you can set up the problem and solve A ballocn filled with 2.00 L of helium initially at 1.55 atm of pressure rises into the atmosphere. When the surrounding pressure reaches 350 mmHg the balloon will burst. If 1 atm 750. mmHg, what volume will the balloon occupy in the instant before it bursts? Express your answer with the appropriate units. View Available Hint(s)

Answer 1

PV=nRT

P= pressure

V= VOLUME

n= no.of moles

R= gas constant

T= temperature
