The ratio of H was approximately $2.4057$. To get whole numbers for the empirical formula, we need to find the smallest integer that, when multiplied by $2.4057$, results in a whole number. Step 1: Approximate $2.4057$ to a simple fraction. $2.4057$ is very close to $2.4$. $2.4$ can be written as a fraction: $$2.4 = \frac{24}{10}$$ This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2: $$\frac{24}{10} = \frac{24 \div 2}{10 \div 2} = \frac{12}{5}$$ Step 2: Use the denominator of the simplified fraction to multiply the ratios. Since the ratio of H is approximately $\frac{12}{5}$, multiplying both the C and H ratios by the denominator (5) will convert both to whole numbers: For C: $1 \times 5 = 5$ For H: $\frac{12}{5} \times 5 = 12$ This gives the whole number ratio of C:H as $5:12$, leading to the empirical formula $C_5 H_{12}$.
