Question 136

The carbonate of a metal $M\text{M}$ has the formula $M2(CO3)3\text{M}_2(\text{CO}_3)_3$ .

The relative formula mass ( $M_r$ ) of this carbonate is 292.

Using this information, calculate the relative atomic mass ( $A_r$ ) of the metal $M\text{M}$ .

(Relative atomic masses: $C=12\text{C} = 12$ , $O=16\text{O} = 16$ )
