The order of arrangement of the compounds from smallest number of moles present to largest number of moles present is as follows: Z < X < Y.

How to calculate number of moles?

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

According to this question, there is 2.00 g sample of compounds X, Y, and Z. The molar mass (in g mol) of X is 50, Y is 35, and Z is 90.

  • moles of X = 2g ÷ 50g/mol = 0.04moles
  • moles of Y = 2g ÷ 35g/mol = 0.057moles
  • moles of Z = 2g ÷ 90g/mol = 0.022moles

This shows that the order of arrangement of the compounds from smallest number of moles present to largest number of moles present is as follows: Z < X < Y.
