Which shows the correct relationship between the molecular formula and the empirical formula for cap c sub 2 cap h sub 10 cap n sub 2 ?

For C₂H₁₀N₂, divide each subscript by the greatest common divisor, 2, to get the empirical formula CH₅N. The molecular formula C₂H₁₀N₂ is therefore 2 times the empirical formula, so the correct choice is “molecular formula is equal to 2 times empirical formula.”
