Question

lucite contains 59.9 g c, 8.06 g h, and 32.0 g o. you want to determine the empirical formula. how many moles of c are in the sample? ? mol c do not round your answer. mol c

Explanation:

Step1: Recall the formula for moles

The formula for calculating the number of moles \(n\) is \(n=\frac{m}{M}\), where \(m\) is the mass and \(M\) is the molar mass.

Step2: Identify the mass and molar mass of carbon

The mass of carbon \(m = 59.9\space g\), and the molar mass of carbon \(M = 12.01\space g/mol\).

Step3: Calculate the moles of carbon

Substitute the values into the formula: \(n=\frac{59.9\space g}{12.01\space g/mol}\approx 4.9875\space mol\).

Answer:

\(4.9875\)
