The molar mass of a compound X(HCO₃)₂ is 146. The atomic weight of X when rounded to the nearest whole number is ________, which is ________.

Question

Quizplus · Accepted Answer

The molar mass of X(HCO₃)₂ is 146. The atomic weight of X can be calculated as follows:Atomic weight of X = Molar mass of X(HCO₃)₂ - 2(Atomic weight of H) - 2(Atomic weight of C) - 6(Atomic weight of O)= 146 - 2(1) - 2(12) - 6(16)= 24Therefore, the atomic weight of X when rounded to the nearest whole number is 24, which is Mg.
