Which sample contains the greatest number of moles of cl? which sample contains the greatest number of moles of? 3.8 mol hcl 4.2 mol naclo3 1.7 mol ch2cl2 2.2 mol mg (clo4) 2?

The sample with greatest number of moles of Cl is calculated as follows

calculate the number of moles of Cl in each sample by multipying mole with number of chlorine molecule

Hcl = 3.8 moles x 1 = 3.8 moles

NaCIO3 = 4.2 moles x 1 = 4.2 moles

CH2Cl2 = 1.7 moles x2 = 3.4 moles

Mg (ClO4) 2 = 2.2 moles x 2 = 4.4 moles

Mg (Cl) 4) 2 sample is the one with greatest number of Cl moles
