11.Find the concentration of solution containing 115 gram sugars in 500ml of water?
Answers
Explanation:
I prepared my sample solution by weighing 1 g of sample (plant sample) and dissolving in 20 mL water. Then, I diluted its 20 folds and measured the concentration by HPLC. After that, I calculated the concentration of sugar by interpolation with a standard curve. Firstly, the result showed that there was 25 mg sugar/L in my sample.
I want to know how much sugar is there in the sample in a unit of g sugar / g sample.
Answer:
Answer:
♡mass of solution = mass of solvents + mass of solutions
♡mass of solution = mass of solvents + mass of solutions mass of solution = 500 + 90 = 590
♡mass of solution = mass of solvents + mass of solutions mass of solution = 500 + 90 = 590 ♡ concentration of solution = mass of solute/ mass of solvents ×100
♡mass of solution = mass of solvents + mass of solutions mass of solution = 500 + 90 = 590 ♡ concentration of solution = mass of solute/ mass of solvents ×100concentration of solution = 90/590×100 = 15.2 %
♡mass of solution = mass of solvents + mass of solutions mass of solution = 500 + 90 = 590 ♡ concentration of solution = mass of solute/ mass of solvents ×100concentration of solution = 90/590×100 = 15.2 %
