What is the number of atoms in 3.54 mol s

Answer : 2.13 ×10^24 atoms

explanation :

- One mole of (S) contains Avogadro’s number of atoms (6.02×10^23 molecules),

- Using cross multiplication,

                      1 mol of (S)             →       6.02 ×10^23 atoms

                      3.54 mol of (S)        →                   ?

Hence, the number of atoms in 3.54 mol S = 3.54 × 6.02 ×10^23 / 1 = 21.31 ×10^23 = 2.13 ×10^24 atoms ..

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
