Concept explainers
(a)
Interpretation:
To calculate the mass of C in 0.688 g of CO2
Concept Introduction:
Molar mass is sum of atomic masses of every atom in a molecule.
Let’s say we have a molecule A2B3. Then,
1 mole of A2B3 contains 2 mole of A atom and 3 moles of B atom
(b)
Interpretation:
To calculate the mass of C in 275 g of C3H6.
Concept Introduction:
