Answer
mass of Carbon = 0.437 g
Explanation
Given:
mass of cinnamaldehyde = 0.5347 g
mass of CO2 = 1.6024 g
mass of H2O = 0.2916 g
moles of CO2 = 0.036410 mol
Required: The mass of C, in cinnamaldehyde
Solution:
mass of C in cinnamaldehyde sample = mass of C in CO2
Now that we know the moles of CO2, we can calculate the mass of C
0.036410 mol CO2 x 12.01 g/mol C = 0.437 g of C
