Final answer:
The maximum mass of carbon dioxide that could be produced is 1.76 grams, with the answer rounded to two significant digits to reflect the precision of the given masses.
Step-by-step explanation:
To find out how many grams of oxygen are in 35 g of C2H2O2, we must first determine the molar mass of C2H2O2 and the mass of oxygen within a mole of C2H2O2. The molar mass is calculated as follows: Carbon (C) has an atomic mass of approximately 12.01 g/mol, Hydrogen (H) is approximately 1.008 g/mol, and Oxygen (O) is 16.00 g/mol. Therefore, for C2H2O2:
- The total molar mass = (2 × 12.01) + (2 × 1.008) + (2 × 16.00) = 24.02 + 2.016 + 32.00 = 58.036 g/mol.
- The mass of oxygen in one mole of C2H2O2 = 2 × 16.00 = 32.00 g.
Now, to find out the mass of oxygen in 35 g of C2H2O2, we use the following proportion:
(32.00 g oxygen / 58.036 g C2H2O2) = (x g oxygen / 35 g C2H2O2)
Cross multiplying to solve for x:
x = (32.00 g × 35 g) / 58.036 g = 19.3 g of oxygen (rounded to one decimal place)
