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

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.

3.68•10^21 particles (correct to 3SF)Explanation:1.45 • xg molecular compound • 1mol/237g • (6.02•10^23)/ 1 mol = 3.6831•10^21 representative particles*6.02•10^23 is Avagadro's number

3.683×10^21 particlesExplanation:Number of particles in a substance = (mass of the substance/molar mass of the substance)×Avogadro's number Given; Mass of compound =1.45gMolar mass of compound =237gAvogadro's number=6.02×10^23Therefore, number of particles = (1.45/237)×6.02×10^23=3.683×10^21 particles

54.26 × 10²³ representative particlesExplanation:Given data:Number of moles of water = 9.01 molNumber of representative particle = ?Solution:one mole of any substance contain 6.022 ×10²³ representative particles.9.01 mol × 6.022 ×10²³ representative particles54.26 ×10²³ representative particles The number 6.022 × 10²³ is called Avogadro number."It is the number of atoms , ions , molecules or representative particles in one gram atom of element, one gram molecules of compound and one gram ions of a substance "

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.
