A sample of abscorbic acid is synthesized in the laboratory. It contains 1.50g of carbon and 2.00 g of oxygen. Another sample of abscorbic acid isolated fro citrus fruits contains 6.35 g of carbon.
Answer:
Absorbic acid is always the same and also the ratio between C and O
1.50 : 2 = 6.35 : x
x = 8.47 g of O
This is more like setting up a maths proportion...try this:
1st sample of absorbic acid contains:
1.5 g Carbon
2.00 g Oxygen
2nd sample of absorbic acid contains:
6.35 g Carbon
? g Oxygen
1.5 g of C ---> 2.00 g of O
6.35 g of C ---> ? g of O
So just set up a proportion:
1.5/6.35 = 2.00/x
1.5x = 6.35 (2.00)
1.5x = 12.7 (divide both sides by 1.5)
x = 8.467 (rounded to 3 decimal places)
Therefore, the second sample of absorbic acid contains 8.467 g of Oxygen.
