QUESTION:
A 4.00-g sample of FeS containing nonsulfide impurities reacted with HCl to give 896 mL of \(\mathrm{H}_{2} \mathrm{S}\) at \(14^{\circ} \mathrm{C}\) and 782 mmHg. Calculate mass percent purity of the sample.
ANSWER:Step 1 of 3
The goal of the problem is to calculate mass percent purity of the sample
Given:
Mass of FeS= 4.00 g
V of \(\mathrm{H}_{2} \mathrm{S}\) = 896 mL
\(\mathrm{T}=14^{\circ} \mathrm{C}=14+273=287 \mathrm{~K}\)
P = 782 mmHg.
