If I have a 1200 gram sample of a soft drink and it contains 180 grams of sugar, the percentage by mass of the sugar in the drink is 15%. If the sugar in the drink is sucrose (C12H22O11), how many grams of pure carbon can be obtained from decomposing all of the sugar in the soft drink?
Pre AP Chemistry -
Find the formula mass of sucrose=342 grams
Part/whole*100 which is 144/342*100=42.1%
42.1% of 180 grams= 76 grams
