There are 14.4 * 10^18 oxygen atoms in 5.0020 mg of strontium bicarbonate.
Mass of strontium bicarbonate Sr(HCO3)2 = 5.0020 mg
Molar mass of strontium bicarbonate Sr(HCO3)2 = 209.6537 g/mol
Number of moles of strontium bicarbonate Sr(HCO3)2 = 5.0020 * 10^-3g/209.6537 g/mol
= moles
Given that we have 6 oxygen atoms per molecule of Sr(HCO3)2, the total number of oxygen atoms in Sr(HCO3)2 becomes;
