Question

the sample has 86 g c and 14 g h. mass to mole: how many moles of h are in 14 g h? 1.17 mol 13.9 mol 14.1 mol

Explanation:

Step1: Recall the formula for moles

The formula to calculate 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 hydrogen

The molar mass of hydrogen \(H\) is \(M = 1.008\space g/mol\).

Step3: Substitute values into the formula

Given \(m = 14\space g\) and \(M=1.008\space g/mol\), then \(n=\frac{14}{1.008}\approx13.9\space mol\)

Answer:

13.9 mol
