Question

a compound has the empirical formula given below. c7h5o2 which compound represents the molecular formula with a scale factor of 2? c3.5h2.5o c14h10o4 c7h5o2

Explanation:

Step1: Multiply each subscript by scale factor

Given empirical formula \(C_7H_5O_2\) and scale factor \(n = 2\).
For carbon: \(7\times2=14\)
For hydrogen: \(5\times 2 = 10\)
For oxygen: \(2\times2=4\)

Answer:

\(C_{14}H_{10}O_{4}\)
