@LesleyCordero Oh shoot, yes I did!  Thanks for catching my mistake...the correct answer for the first problem should be 84.1 L.  I'll fix it on the video as soon as I have a chance!

@stoverma

your tutorials have all been very useful! you explain the concepts great! thxs!

@Oceanbreezen

your vids are the most helpful on youtube..thanks!

@TheChemistrySolution

depends on what value you use for the ideal gas constant.  In these examples, the units for the ideal gas constant I used were (L x atm)/(mol x K), so you will notice that the temperature values, although given in Celcius in the problem, were converted to Kelvin in the calculation.

@gr3g0rus

Helps so much, thank you!

@Chameleonslove

Thanks alot

Helped me with my homework

@19ligram

What If, when the value of R (constant Ideal Gas) will be on value, 0.08206? 

@TheChemistrySolution

That is the value I used, I just rounded to 0.0821.

What would the mass of air be inside a hot air balloon that has the volume of 5.25 x 10^4 L. The temperature of the air inside is 30 degrees celsius and the pressure is 95.5 kPa. Assume the composition of air is 80% nitrogen gas and 20% oxygen gas to determine the molar mass of air.

IDEAL GAS LAW MUST BE IN KELVIN!!!!

Ok, but not wonderful pedagogy.
