The empirical formula for this vitamin : C₃H₄O₃
<h3>Further explanation
</h3>
The empirical formula is the smallest comparison of atoms of compound =mole ratio of the components
The principle of determining empirical formula
- Determine the mass ratio of the constituent elements of the compound.
- Determine the mole ratio by dividing the percentage by the atomic mass
Mass of C in CO₂ :(MW C = 12 g/mol, CO₂=44 g/mol)
Mass of H in H₂O :(MW H = 1 g/mol, H₂O = 18 g/mol)
Mass O = Mass sample - (mass C + mass H) :
mol ratio C : H : O =
Answer:f has 14 electrons in 7 sublevel orbitals,d has 10 electrons in 5 sublevel orbitals,p has 6 electrons in 3 sublevel orbitals,s has 2 electrons in 1 sublevel orbital.

Answer:
N = 5.8 × 10²⁴ molecules
Explanation:
Step 1: Given and required data
- Moles of C₂H₄ (n): 9.6 mol
- Avogadro's number (NA): 6.02 × 10²³ molecules/mol
Step 2: Calculate the number of molecules (N) in 9.6 moles of C₂H₄
To convert moles to molecules we need Avogadro's number: there are 6.02 × 10²³ molecules of C₂H₄ per mole of C₂H₄
N = n × NA
N = 9.6 mol × 6.02 × 10²³ molecules/mol
N = 5.8 × 10²⁴ molecules
