aspartame is an artificial non-saccharide sweetener that is commonly used as a substitute to sugar. it is usually consumed by people suffering from diabetes, enabling them to enjoy sweet-tasting foods without carbohydrates. calculate the percentage composition of all elements present in aspartame, if its chemical formula is C14H18N2O5
Step 1: Calculate the molar mass of C₁₄H₁₈N₂O₅.
Note that the molar masses of C, H, N, and O are 12.011 g, 1.008 g, 14.007 g, and 15.999 g, respectively.
Step 2: Solve for the percentage composition of C₁₄H₁₈N₂O₅.
• For C
• For H
• For N
• For O
Hence, aspartame is composed of 57.14% C, 6.16% H, 9.52% N, and 27.18% O by mass.
