Convert 1.65 × 1024 atoms of carbon to moles of carbon.

The number of moles in a substance indicates the amount of the substance that contains the same number of particles as 12 g of the Carbon-12 isotope [or equivalent to 6.02 × 10²³] (which is used as a standard in the world of moles).

Now,

          if     6.02 × 10²³ atoms are found in 1 mole of C
   then let  1.65 × 10²⁴ atoms are found in     x

⇒     x  =    (1.65 × 10²⁴)  ÷  (6.02 × 10²³)

            =  2.7409 mol


A sample of 1.65 × 10²⁴ atoms of Carbon (C) would contain ~ 2.74 mol  

Aconductor easily transfer heat

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
