  • 2.6 angstrom is 0.26 nanometer, not 0.026 nanometer.

  • Mol-AR-ity is measure that will v-AR-y.

    Mol-ALITY is a measure that has fin-ALITY

  • In regards to the beginning, I think you mean "homogeneous" mixtures, not "homogenous". Could confuse some chemistry+biology students. Similarly, it's "heterogeneous," not "heterogenous".
