Typically, there is a scale provided for weighing the nails. For example, a notice placed above the nail bin might read, “For the nails in the bin below, there are 500 nails per kg.” Using this conversion factor, perform the following calculations.
How many nails would you have if you had 0.15 kg?
If you had 12 dozen nails, what would be their mass?
What is the mass of one nail?
What is the mass of 2.3 moles of nails?

I already answered the first question for you.
