Question

multiply across the bottom of the unit conversion. what is the product of the denominator? 24 moles c₂h₆ | 7 moles o₂ / 2 moles c₂h₆ = 168 / ? do not round or reduce the answer.

Explanation:

Step1: Multiply the denominators

We have the unit conversion \( \frac{24\space moles\space C_2H_6}{2\space moles\space C_2H_6}\times\frac{7\space moles\space O_2}{1}\) (the second fraction can be thought of as \(\frac{7\space moles\space O_2}{1}\)). The denominator of the first - fraction is \(2\space moles\space C_2H_6\) and the denominator of the second - fraction (in a sense, when we consider the overall unit - conversion multiplication) is \(1\). But if we consider the cross - multiplication for the denominator in the unit - conversion setup given \(\frac{24\space moles\space C_2H_6\times7\space moles\space O_2}{2\space moles\space C_2H_6}\), the denominator is \(2\).

Answer:

\(2\)
