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 ..

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
