Web11 mrt. 2024 · The mass percent of lithium in L i 2 C O 3 is calculated as follows: Mass percent = 2 M Li M L i 2 C O 3 × 100 % ∴ Mass percent = 13.88 73.89 × 100 % = 18.78 % Hence, the mass percent of lithium in lithium carbonate is 18.78%. Note: The total sum of percentage composition of each element present in a compound is always equal to 100%. WebScience Chemistry Find in the chemical literature at least three values for the molar mass of lithium determined since 1910 and arrange them chronologically in a table or spreadsheet along with the values since 1817 given in the table on page 10 of the paper by Richards and Willard. Construct a graph of molar mass vs. year to illustrate how the …
