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%

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 can follow these steps:

1. Calculate the concentration for each drink:
- For Coke: Divide the amount of sugar (65g) by the volume of the drink (591ml): 65g/591ml = 0.11g/ml or 11%.
- For Gatorade: Divide the amount of sugar (grams) by the volume of the drink (ml) to get the concentration.

2. For the calculation, you can find the 1000ml concentration using the formula: (591/1000) * 65g = concentration in grams.

Regarding the calculation of absolute errors for the measured sugar concentrations:

1. Take the difference between the measured concentration and the reference concentration (values determined earlier).
2. Take the absolute value of the difference to ensure positive values.

For example, if the measured concentration was 10% and the reference concentration was 11%, the absolute error would be |10% - 11%| = 1%. Repeat this calculation for each measured concentration to determine the absolute errors.

To determine the concentration of sugar in each drink, you need to use the information from the nutrition label of each drink. Let's calculate the concentration of sugar in each drink step-by-step:

For Coke:
- The label states that there are 65g of sugar in a 20 oz (591 ml) serving.
- To find the sugar concentration per milliliter, divide 65g by 591ml:
65g / 591ml = 0.11g/ml
- To convert this to a percentage, multiply by 100:
0.11g/ml * 100 = 11%

So, the concentration of sugar in Coke is 11%.

Now let's move on to Gatorade:
- The label states that there are 1.5g of sugar in a 20 oz (591 ml) serving.
- To find the sugar concentration per milliliter, divide 1.5g by 591ml:
1.5g / 591ml = 0.0025g/ml
- To convert this to a percentage, multiply by 100:
0.0025g/ml * 100 = 0.25%

So, the concentration of sugar in Gatorade is 0.25%.

Now, let's calculate the absolute errors of measured sugar concentrations. The reference values for the measured sugar concentrations are the values you previously calculated for sugar solutions 1, 2, and 3. Here's how you can calculate the absolute errors:

For sugar solution 1:
Absolute error = |concentration of sugar solution 1 (3.6%) - sugar concentration of Coke (11%)|

For sugar solution 2:
Absolute error = |concentration of sugar solution 2 (7.2%) - sugar concentration of Gatorade (0.25%)|

For sugar solution 3:
Absolute error = |concentration of sugar solution 3 (10.6%) - sugar concentration of Coke (11%)|

By substituting the values and calculating the absolute differences, you can find the absolute errors for each measured sugar concentration.
