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

Explanation:

Step1: Use 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. The molar mass of \(H\) is \(M = 1.008\space g/mol\), and the mass of \(H\) is \(m=8.06\space g\).

Step2: Calculate the moles of \(H\)

Substitute the values into the formula: \(n=\frac{8.06\space g}{1.008\space g/mol}\)

$$n=\frac{8.06}{1.008}\space mol\approx 7.996032\space mol$$

Answer:

\(7.996032\)
