Question

A student repeated the experiment with a different Group 2 metal carbonate (XCO3).
The relative formula mass (Mr) of XCO3 is 84
Relative atomic masses (Ar): C = 12 O = 16
Calculate the relative atomic mass (Ar) of X.
Name metal X.

Answer 1

Relative atomic mass of x is 84-60 = 24 which is that of Mg so x is magnesium. ....please mark as brainliest
