1. The problem statement, all vbles and given/known data
So I'm going throught the Nova Physics book and I'm wondering if there's a mistake in calculation. The question reads: How much volume does 0.4kg of oxygen gas take up at T= 27 degrees Celsius and P= 12 atm (gas constant R = 0.0821 L atm/ K Mol).
V= nRT/ P
the text's last two steps for this calculation are: 0.4x1000x0.08x300 / 32 x 12
the last calculation is: 4x8x300 / 8x50 giving an answer of 24 L.
Where on Earth did the 8x50 denominator come from?
I keep coming up with 25L, but the textbook calculates the volume to be 24L.
Thanks in advance for any help offered :)
