The relative formula mass (Mr) of a Group 2 metal carbonate is 197Rela

1.	The relative formula mass (Mr) of a Group 2 metal carbonate is 197Relative atomic masses (Ar): C = 12 O = 16Calculate the relative atomic mass (Ar) of the Group 2 metal in the metal carbonate.Name the Group 2 metal.
Answer» X = is the atomic relative MASS of the group 2 METAL. X + 12 +16= 196 X + 28 = 196 X = 196 - 28 X = 168 the atomic relative mass of the atom of group 2 is 168 so the metal is tellerium

Answer»

X = is the atomic relative MASS of the group 2 METAL.

X + 12 +16= 196

X + 28 = 196

X = 196 - 28

X = 168

the atomic relative mass of the atom of group 2 is 168

so the metal is tellerium
