Ответ:
0.0305 moles of MgCO₃
Explanation:
In order to solve this problem, we first need to calculate the molecular weight of MgCO₃:
MgCO₃ MW = Atomic mass Mg + Atomic mass C + (Atomic mass O)*3MgCO₃ MW = 24.3 + 12 + 16*3 = 84.3 g/molFinally we divide the mass by the molecular weight, to calculate the number of moles:
2.57 g MgCO₃ ÷ 84.3 g/mol = 0.0305 moles.Ответ:
