Verified step by step guidance1
Understand that atomic mass can be expressed in different units such as kilograms (kg), atomic mass units (amu), and daltons (Da). 1 amu is equivalent to 1 Da.
Convert the mass of Element A from kilograms to atomic mass units (amu). Use the conversion factor: 1 kg = 6.022 x 10^26 amu.
Convert the mass of Element C from kilograms to atomic mass units (amu) using the same conversion factor: 1 kg = 6.022 x 10^26 amu.
Compare the atomic masses of Element A, Element B, Element C, and Element D, ensuring all are in the same unit (amu or Da) for a fair comparison.
Identify the element with the greatest atomic mass by comparing the numerical values obtained after conversion.
