Answer:
Carbon has the highest mass percent
Explanation:
Step 1: Data given
Predict the element that will have the highest mass percent composition in each compound without doing any calculations.
For C3H6O, carbon will have the highest mass percent. The molar mass of of Oxygen and carbon are more or less the same. But we have 3x more Carbon than oxygen.
Identify the element that has the highest mass percent composition in C3H6O .
atomic mass C = 12.01 g/mol
atomic mass O = 16.0 g/mol
atomic mass H = 1.01 g/mol
molar mass C3H6O = 58.08 g/mol
%C = (3*12.01 / 58.08) * 100 %
%C = 62.04%
%O = (15.99 /58.08) *100%
%O = 27.53 %
%H = (6*1.01 / 58.08) * 100%
%H = 10.43
Carbon has the highest mass percent
The element that will have the highest mass percent composition in the compound is carbon
Description of the compound, C₃H₆O
From the formula of the compound (i.e C₃H₆O), we have:
- Mass of C = 3 × 12 = 36 g
- Mass of H = 6 × 1 = 6 g
- Mass of O = 1 × 16 = 16 g
Highest percentage composition
The element with the highest percentage composition can be obtained as follow:
- Mass of C = 36 g
- Mass of H = 6 g
- Mass of O = 16 g
From the above, we can see that carbon (C) has the highest mass (i.e 36 g) in the compound.
This simply means that carbon will have the highest mass percent in the compound.
