Question

Nitrogen is maintained at 152 kPa in a 2.00-dm^3 vessel at 298.15 K. If its molar mass is 28.0134 g/mol, calculate: (a) The amount of N2 present (ans: 0.123 mol) (b) The number of molecules present (ans: 7.41 x 10^22) (c) The root-mean-square speed of the molecules (ans: 515.2 m/s) (d) The average translational kinetic energy of each molecule (ans: 6.174 x 10^-21 J) (e) The total translational kinetic energy in the system (ans: 457 J)

Step 1

We are given P, V, and T, and we want to find n. We will use the value of R = 8.314 J/(mol·K). 152 kPa * 2.00 dm³ = n * 8.314 J/(mol·K) * 298.15 K Show more…
