Answer 2

Step by step explanation:

Given : A compound Magnesium carbonate.

To find : The molecular mass of compound.

Formula used : Molecular mass of compound $A_xB_y$ is,

Molecular mass = $x$ × Molar mass of A + $y$ × Molar mass of B.

• Calculation for molecular mass of magnesium carbonate

The formula of Magnesium carbonate is $MgCO_3$  in this compound we have total five atoms ; one Magnesium(Mg) , one carbon(C) and three oxygens (O).

The molar mass of Magnesium(Mg) is $24.31 g/mol$

The molar mass of Carbon(C) is $12g/mol$.

The molar mass of Oxygen(O) is $16g/mol$.

Now the molecular mass of $MgCO_3$ ,

⇒  Molecular mass of $MgCO_3$ $=1*24.31+1*12+3*16$

                                                    $=24.31+12+48$

                                                    $=84.31 g/mol.$

Hence the molecular mass of magnesium carbonate is $84.31g/mol$.
