How many particles are in 42g of CO

One mole of any element/compound has a mass equal to its gram atomic/molecular mass.

We know that Carbon has an atomic mass equal to 12g, I. E. One mole of carbon atoms weighs 12g.

We know that one mole of any substance contains 6.0225X10^23 particles(atoms, molecules, ions, etc.).

Thus 12g of Carbon contains 6.0225X10^23 atoms of Carbon. Therefore 1g Carbon will contain (6.0225X10^23)/12 atoms of Carbon.

Answer= 5.01875 X 10^22 atoms

explanation:

there is no explanation

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
