  5. What is the apparent molarity of Citral, Products W230316, C83007, and W230308?

    The apparent molarity of a neat liquid may be calculated from the density and molecular weight.  In the case of citral, the density is 0.888 g/mL and the molecular weight is 152.23 g/mole. By writing the density as 888 g/L, the calculation is 888 g/L divided by 152.23 g/mole = 5.83 mole/L, or 5.83 M.
