Question

Following are atomic masses of a few elements in
Use your brain power ! Dalton and the molecular formulae of some compounds.
Deduce the molecular masses of those compounds.
Atomic masses → H(1), O(16), N(14), C(12), K(39), S(32) Ca(40), Na(23), C (35.5)
Mg(24), Al(27)
Molecular formulae → NOCI, MOCI, KNO,,H,O, AICI, Ca(OH), MgO, H.SO,
HNO, NaOH
​

Answer 1

NOCl = 14+16+35.5 = 65.5

MOCl = what is M here

KNO = 39+14+16 =69

H= 1

O = 16

AlCl = 27+35.5 = 62.5

Ca(OH)= 40+16+1 = 57

MgO =24+16=40

HSO=1+32+16=49

HNO=1+14+16=31

NaOH=23+16+1=40

Hope it helped you dear friend
