Question

arrange the following in order of increasing mass of 1 mole--- CO3^3 po4^3,

Answer 1

Please find the solution to the asked query:

Mass of one mole of CO32-.
Mass of 1 mole is same as the molar mass of CO32- , so : molar mass of Carbonate ion is 60g/mol [12+16x3 =60]

Mass of one mole of PO43-
Mass is : [30+16 x 3 =94g/mol]

Mass of one mole of SO42-
Mass is : [32+16 x4= 96g/mol]

Mass of one mole of Cl-:   35g/mol
Mass of one mole of S2- : 32g/mol

​Increasing order of masses:
S2-<  Cl-< CO32- <  PO43-< SO42-
Hope this information will clear your doubts regarding the topic.
