Science Chemistry Mass of empty evaporating dish + watch glass 65.362 g B Mass of dish + watch glass + initial solid 65.864 g C Mass of dish + watch glass + carbonate 65.705 g D Mass of dish + watch glass + chloride 65.716 g Use the data to calculate the mass (in grams) of the carbonate that Jack obtained after the initial heating of his unknown solid. (e) C6H12O6 (glucose), (a) the anesthetic halothane, C2HBrClF3 Rest when it comes to calculate mass percent, then using this mass percent calculator chemistry is the only choice left for you that is trustworthy. Following is a picture outlining these ideas. Calculate the percent by mass of the element listed first in the formula for nitrogen dioxide, NO2. 2.171 cm x 4.20 cm b. To calculate the percent by mass of nitrogen, divide the atomic mass of nitrogen by the mass of the compound and then multiply by 100.
