Answer:
0.60 moles of atoms of carbon
Explanation:
Step 1: Given data
- Chemical formula of the compound: Mg(HCO₃)₂
- Moles of oxygen atoms: 1.8 moles
Step 2: Calculate the number of carbon atoms in the given sample
According to the chemical formula of the compound, the molar ratio of C to O is 2:6, that is, there are 2 moles of atoms of C every 6 moles of atoms of O. The number of moles of atoms of C is:
1.8 mol O × 2 mol C / 6 mol O = 0.60 mol C
