Question

a certain organic compound o has a solubility in hexane of 66.0\\(\frac{g}{l}\\) at 5.\\(^{\circ}\\)c. calculate the greatest mass of o that could be dissolved in 6.0 l of hexane at this temperature. you may assume the volume of the solution doesnt change as the o is dissolved. be sure your answer has the correct unit symbol and number of significant digits.

Explanation:

Step1: Set up the proportion

The solubility is \(66.0\frac{g}{L}\), which means for every \(1\ L\) of hexane, \(66.0\ g\) of \(O\) can dissolve. Let \(m\) be the mass of \(O\) that dissolves in \(V = 6.0\ L\) of hexane. We use the formula \(m=\text{solubility}\times V\).

Step2: Calculate the mass

Substitute the values into the formula: \(m=66.0\frac{g}{L}\times6.0\ L\).
