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 o are in the sample? ? mol o do not round your answer. mol o

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 molar mass of oxygen

The molar mass of oxygen (\(O\)) is \(M = 16.00\space g/mol\).

Step3: Calculate the moles of oxygen

Given \(m = 32.0\space g\) of \(O\), using the formula \(n=\frac{m}{M}\), we substitute the values: \(n=\frac{32.0\space g}{16.00\space g/mol}\)

Answer:

\(2.00\space mol\)
