To calculate the grams of LiCl needed to react with 200.12g of Br2, first divide the mass of Br2 by its molar mass to find the number of moles of Br2. Use the stoichiometry from the table to determine the ratio between Br2 and LiCl, and then convert moles of Br2 to moles of LiCl. Finally, multiply the moles of LiCl by its molar mass to find the grams needed. The result should be rounded to 2 decimal places.
