Question
Using the data solve this: The mass of zinc found on each nail can then be used to determine how much it should cost to galvanize 100 nails considering zinc costs $2.86/kg.
Data if different nail is coated with a 0.053 cm thick layer of zinc and the surface area of the nail is 8.59 cm2: B. mass = 3.246g (Use density = 7.13g) A. volume = 0.45527cm3 (use given info) Volume = 0.053cm × 8.59cm² Mass = 0.45527 x 7.13 C. moles = 0.0496 moles (use M) D. Zn atoms = 2.988 × 1022atoms (use NA) 1 atoms of Zn = 6.022 × 1023 atoms 0.0436 mole of Zn = 6.022 x 1023 x 0.0436 3.246 Moles = 65.38 Mass of a single zinc atom in grams: Mass of single atom = 1.0863 x 10-2 g
