2. Calculate the density of of air at 25.00C and 1.0 atm. It’s average molar mass under these conditions is 28,96 g/mol a. 1.18 g/L b. 11.8 g/L c. 18.1 g/L 81.1 g/L

An electron is trapped at a defect in a crystal. the defect may be modeled as a one-dimensional, rigid-walled box of width 1.00 nm. (a) sketch the wavefunctions and probability densities for the n 1 and n 2 states. (b) for the n 1 state, nd the probability of nding the electron between x1 0.15 nm and x2 0.35 nm, where x 0 is the left side of the box. (c) repeat (b) for the n 2 state. (d) calculate the energies in electron volts of the n 1 and n 2 states
