I need help on my chem lab... I need to give you background info so you know how to help me..

Data Sheet:
Specific gravity of distilled water
Temp of distilled water = 20 C
Specific gravity: 1.0000 or 1.000 (according to hydrometer used)
sugar solution 1 : mass 18.01 g volume 500 ml specific gravity 1.014
sugar solution 2 36.01g 500 ml 1.027 SG
sugar solution 3: 52.98 g 500 ml 1.039 sg

specific gravity of regular coke: 1.050
of gatorade: 1.025

1. Calculate the density of distilled water used.
Answer I got: specific gravity is 1.000
density is SG*1000kg/m^3 = 1*1000 kg/m^3 or just 1g/cm^3

2. calculate the concentration in % of standard sugar solutions
Answer I got:
sugar solution 1 (18.01/500)=.036*100=3.6%
sugar solution 2
(36.01/500) = 0.072*100= 7.2%
sugar solution 3
(52.98/500) = 0.106*100= 10.6%

**** Help here***
Using information (sugar and serving size) on nutrition label of each drink, determine the concentration of sugar in each drink. Show calculations?
Coke 20 oz = 65g sugar per 591 ml
So, would I first find the 1000ml?? do I calculate 591/1000 * 65g = 38.4%?? or is it just 65g/591 = 11%?? confused how to work this

***** Help with how to work this****

Calculate the absolute errors of measured sugar concentrations by using the values determined in the previous problem as reference values.....

How do I calculate this ??? Help!!!

To determine the concentration of sugar in each drink based on the information on the nutrition label, you need to consider the serving size and the amount of sugar stated.

For Coke, you have the information that it contains 65g of sugar per 591ml. To find the concentration in %, you can calculate the ratio of sugar to the serving size.

First, convert the serving size to 1000ml for consistency:

591ml / 1000ml = 0.591

Then, calculate the sugar concentration:

0.591 * 65g = 38.215g

To express this as a percentage, divide the sugar concentration by the total volume and multiply by 100:

38.215g / 1000ml * 100 = 3.8215%

So, the concentration of sugar in Coke is approximately 3.8215%.

For Gatorade, follow the same process using the information provided on the nutrition label.

To calculate the absolute error of measured sugar concentrations, you need to compare them to the reference values you calculated earlier for the standard sugar solutions.

For example, let's say you previously determined that the concentration of sugar in sugar solution 1 is 3.6%. If you measure a different concentration, let's say 3.8%, you can calculate the absolute error as follows:

Absolute Error = |Measured Value - Reference Value|

Absolute Error = |3.8% - 3.6%| = 0.2%

Repeat this calculation for each measured sugar concentration using the corresponding reference value to determine their absolute errors.
