RE: Chemistry quiz 2: win up to 6 steem! :)
2.5 m
There's 7.79215x10^26 N2 molecules. A single molecule = 14.007u. So you work out the total mass contained within the subset of consideration: (total number of N2 molecules ) x (2 x weight of single N molecule). Then consider the density of the subset of the mass rho = 0.75518 x 1.2. Then density = mass/ volume => height = mass/(16x1.2x0.75518)
Congrats, that's the correct solution!
You are the winner of this round.
That was really creative to calculate the heigth of the room by the number of N2 molecules in it!
Congrats . Now, i know where I'm off.
Excellent work
