Solution

Arrangement of masses of atoms in same power of 10 is given by
Titanium= $7.95 \times 10^{- 26}$
Lead= $34.4 \times 10^{- 26}$
Silver= $17.9 \times 10^{- 26}$
Lithium= $1.15 \times 10^{- 26}$
Hydrogen= $0.1674 \times 10^{- 26}$
Thus, we have
34.4 > 17.9 > 7.95 > 1.15 > 0.1674
Arrangement of elements in order from lightest to heaviest is given by
Hydrogen < Lithium < Titanium < Silver < Lead
