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
