Unformatted text preview: Normalize the numbers relative to 100 atoms of the most abundant element. For example, in Table 3a, the result will be 100 hydrogen atoms, followed by about 10 helium atoms, etc. Table 3a. Abundance of Elements in Universe Element Mass % Number of moles in 100 g sample Normalized relative number of atoms H He O C N Ne Be Table 3b. Abundance of Elements in Earths Crust Element Mass % Number of moles in 100 g sample Normalized relative number of atoms O Si Al Fe Ca Na K Mg Ti H P Mn 4. Calculate the concentration (mmol/L) of from the mass percent for the following elements in sea water. (Note: I wrote mol/L on the board in the classroom. Lets change that to mmol/L.) Assume the density of sea water to be 1.0 g/mL. Element Mass % mmol/L Cl 1.94 Na 1.08 Mg 0.13 S 0.09 Ca 0.04 K 0.04...
