While the terms 'meta-analysis' (a statistical method to combine the results of primary studies), or sometimes 'narrative synthesis', are frequently used to describe how quantitative research is synthesised, far more terms are used to describe the synthesis of qualitative research.
If your question is asking about the equivalent of teaspoons of sugar for the number of grams of sugar a 12 fl oz can of Coca-Cola Classic, then the answer is approximately 10 teaspoons. One can of Coke has 39g of sugar and 1 teaspoon of sugar is the equivalent of 4g of sugar. Answer: approx 10 teaspoons.
A 12 oz can of Coca-Cola contains 39g of sugar, which is almost 8 teaspoons, whereas Pepsi contains 41g of sugar, closer to about 8.2 teaspoons. Pepsi also uses sweeteners, making it the much sweeter beverage. As far as caffeine goes, a can of Pepsi contains 38mg of it, whereas Coke has 34mg. Annually, Coke sells 2.3 billion gallons of Coca-Cola Classic in the U.S. alone, which is about 6.4 million gallons every single day, while Pepsi sells just over half that with 1.2 billion gallons of Pepsi Cola in the U.S, or about 3.4 million gallons a day
