Describe how you would prepare 100ml solution of 40 brix sucrose

To add 40g of sucrose into 60g of water.

Explanation:

°Brix represents amount of sucrose in an aqueous solution. 1 Degree brix represents 1g of sucrose in 100g of solution.

As you want to prepare 100mL of solution of a 40°brix and assuming a density of the solution of 1g/mL you need 100g of solution (100g = Mass solute + Mass solvent) and 40g of sucrose. That means mass of water must be:

100g = Mass solute (Sucrose) + Mass solvent (Mass water).

100g = 40g + Mass Water

60g = Mass of water.

Thus, to prepare a 40°brix solution you need:

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
