Question

How many liters of gas can be collected at 25 C and 0.98atm if 0.063 grams of zinc metal fully reacts in a solution of hydrochloric acid. A 15.5% error was calculate for this reaction, what was the actual volume collected in this experiment?

Answer 1

T=25⁰C

P=0.98atm

if 0.063g react then 0.63/65.4=0.0096moles react to give 0.0096 moles of H₂ gas

Zn+2HCl = ZnCl₂ + H₂

$V=nRT/P$

V=(0.0096*8.314*298)/0.98= 24.27m³

1000L=1m³

V=24270L
