Question

there are 4.9875 mol c, 7.9802 mol h, and 2.00 mol o in the sample. divide each by the smallest number of moles. what is the ratio for the c? do not round your answer.

Explanation:

Step1: Identify the smallest number of moles

The number of moles of \(C = 4.9875\), \(H=7.9802\), \(O = 2.00\). The smallest number of moles is \(2.00\) (for \(O\)).

Step2: Calculate the ratio for \(C\)

Divide the number of moles of \(C\) by the smallest number of moles. The ratio for \(C\) is \(\frac{4.9875}{2.00}=2.49375\).

Step3: Calculate the ratio for \(H\)

Divide the number of moles of \(H\) by the smallest number of moles. The ratio for \(H\) is \(\frac{7.9802}{2.00}=3.9901\).

Step4: Calculate the ratio for \(O\)

Divide the number of moles of \(O\) by the smallest number of moles. The ratio for \(O\) is \(\frac{2.00}{2.00}=1\).

Answer:

\(2.49375\) \(C:3.9901\) \(H:1\) \(O\)
