Question

7 multiple choice 1 point calculate the molecular mass of caco₃. periodic table of the elements 88.08 amu 40.08 amu 100.08 amu 108.00 amu clear my selection

Explanation:

Step1: Identify atomic masses

From the periodic table, atomic mass of Ca is \(40.08\) amu, C is \(12.01\) amu, O is \(16.00\) amu.

Step2: Calculate molecular mass

For \(CaCO_3\), molecular mass = mass of Ca + mass of C + 3×mass of O.
So, \(40.08 + 12.01 + 3\times16.00 = 40.08 + 12.01 + 48.00 = 100.09\) (approx \(100.08\) amu).

Answer:

100.08 amu (the option with "100.08 amu")
