CREATE TABLE table_71348 ("Molecule" TEXT, "Percent of Mass" TEXT, "Mol.Weight  ( daltons ) " TEXT, "Molecules" TEXT, "Percent of Molecules" TEXT)

what is the percent of mass when the mol.weight (daltons) is 1e11?
SELECT "Percent of Mass" FROM table_71348 WHERE "Mol.Weight (daltons)" = '1e11'
SELECT "Percent of Mass" FROM "table_71348" WHERE "Mol.Weight (daltons)" = '1e11'
