Since all these elements are in the same conditions of volume, only varies according to the number of atoms present. You can find the number of atoms in a given sample by dividing the weight of the sample by the molar mass.Aluminum has a molar mass of 26.9 for the 10/26.9 = .371 molesgo about Ti= 10 / 47.88 =.209 molesMg = 10.0 / 24.3 = 0.412 molesZn = 10 / 65.37 = .153 molesSince there are less moles of Zn, has the smallest volume at STP than the other elements.
