Answer:
the mass of C present in 44g of CO₂ is 12g.
Explanation:
Given,
mass of CO₂ = 44g
molar mass of CO₂ = 12 + 2×16 = 44g/mol.
moles of CO₂ = mass of CO₂ / molar mass of CO₂
⇒ = 44g / 44gmol⁻¹ = 1 mol.
one molecule of CO₂ contains one C atom.
one mole of CO₂ contains one mole of C atom.
one mole of C atom weighs its atomic weight, 12g.
Thus, the mass of C present in one mole of CO₂ is 12g.
