- Young's modulus for aluminum is 6.2 x 1010 N/m2. The density of aluminum is 2.7 grams/cm3, and the mass of one mole (6 x 1023 atoms) is 27 grams. If we model the interactions of neighboring aluminum atoms as though they were connected by springs, determine the approximate spring constant of such a spring. Repeat this analysis for lead: Young's modulus for lead is 1.6 × 1010 N/m?, the density of lead is 11.4 grams/cm3, and the mass of one mole is 207 grams. Make a note of these results, which we will use for various purposes later on. Note that aluminum is a rather stiff material, whereas lead is quite soft. Part 1 Your answer is incorrect.
