The element that has the greatest mass is 2 moles of pottasium (K). Details about mass can be found below.

How to calculate mass?

The mass of a substance can be calculated by multiplying the number of moles of the substance by its molar mass.

The molar mass of the given elements are as follows:

  • H = 1g/mol
  • K = 39g/mol
  • Mg = 24g/mol
  • He = 4g/mol

This means that the mass of the respective elements are as follows:

  • 1 mole of H = 1g
  • 2 moles of K = 2 × 39 = 78g
  • 3 moles of Mg = 3 × 24 = 72g
  • 4 moles of He = 4 × 4 = 16g

Therefore, the element that has the greatest mass is 2 moles of pottasium (K).
