Ratio by mass of the following compounds
given below :
1) CaCO :
Molar mass of calcium = 40 g
Molar mass of oxygen = 16 g
Molar mass of carbon = 12 g
Hence , ratio by mass will be = 40 : 12 : 48
= 10 : 3 : 12
2) MgCl :
Molar mass of magnesium = 12 g
Molar mass of chlorine = 35.5 g
Hence , ratio by mass will be = 12 : 71
3) H SO :
Molar mass of hydrogen = 1 g
Molar mass of sulphur = 32 g
Molar mass of oxygen = 16 g
Hence , ratio by mass = 2 : 32 : 64 = 1 :
16 : 32
4) C H OH :
Ratio by mass = 24 : 6 : 16 = 12 : 3 : 8
5) NH :
Molar mass of nitrogen = 14 g
Ratio by mass = 14 : 3
6) Ca(OH) :
Ratio by mass = 40 : 32 : 2 = 20 : 16 : 1
