Question
If the following mass and volume data are used to calculate the density of solution, how many significant figures are allowed in the calculated density? Mass of solution = 12.53 g; volume of solution = 8.27 mL According to its nutritional label, orange soda contains 49 g of sugar per 355 mL serving. If the density of the beverage is 1.043 g/ml, what is the percent sugar concentration in orange soda? The sodas should be "flat" in order to achieve the most accurate results. What is the problem with using non-flat sodas?Explanation / Answer
You should always remember to give the results with the number of the smallest significant figures given in your data
2) we have 49 g of sugar per 355 mL of serving
d= 1.043 g /mL
with the desnity we convert the mL to grams to calculate the total mass of the serving
d = m/v
m = d*v = 1.043 g /mL * 355 mL
m= 370.265 g = 370 g
Then to calculate the %
% = g of sugar/ g of total serving * 100
% = 49 g / 370 g * 100
% = 13.24 % = 13 %
3) Flat soda is when you have opened a can or bottle of soda and it has lost it's carbonation (the bubbles).
Thisis done to to remove dissolved carbon dioxide before testing, so it will not interfer in the analysis of the concentration of sugar thata you are doing. also If this is not done, the carbonation can produce bubbles during pipetting and throw off the results
