1 mole 6.02x10²³ molecules4.00 moles ( molecules )molecules = 4.00 x ( 6.02x10²³) / 1molecules = 2.41x10²⁴ / 1 =  2.41x10²⁴ moleculeshope this helps!... Show More

3.68 x 10^21 particlesExplanation:Based on Avogadro's law: 1 mole of any substance has 6.02 x 10^23 atomsSince 1 mole is the same as molar mass of a substance 237 g = 6.02 x 10^23 atoms 1.45g = Z atoms To get the value of Z, cross multiply:(Z atoms x 237g) = (6.02 x 10^23 atoms x 1.45g)237Z = 8.729 x 10^23 Z = (8.729 x 10^23 / 237)Z = 3.68 x 10^21Thus, there are 3.68 x 10^21 representative particles in 1.45 g of the molecular compound....

Explanation:According to Avogadro's number, in 1 mole there are atoms or particles.Since, it is given that there is 4.00 mole sample of a substance. Therefore, calculate the number of representative particles present in it as follows.                   atoms/mol                  = 24.092 atomsThus, we can conclude that there are 24.092 atoms in a 4.00 mole sample of a substance....
