Galvanized nails are iron nails that have been plated with zinc to prevent rusting. the relevant reaction is zn2+(aq)+2e−→zn(s) for a large batch of nails, a manufacturer needs to plate a total zinc mass of 3.40 kg on the surface to get adequate coverage. part a how many moles of zinc are in 3.40 kg of zinc? express your answer to three significant figures and include the appropriate units.

52.0 moles

Explanation:

no. of moles of Zn =

The important part in this question is changing the kilograms to grams so that the units of the mass(grams) are divisible by the units of the molar mass (grams/molar mass)

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

ill try to . no promises tho.
