calculate the number of atoms in 50 dm3 nitrogen gas

Answer 1

I assume at STP. Pressure, and temperature matter.

well, at STP, in 22.4 dm^3 there are avagrado's number of N2 molecules, so atoms would be twice that.

answer: (50/22.4)2*avagrados number

Answer 2

1mole =22,4dm
x mole of NA = 50dm^3
x=2.23

1 mole N2= 2{6,02.10^23)
2.23moles of N2= x atoms
x= 2,68.10^24
