Question

When the experiment was carried out, the temperature was 22 oC and atmospheric pressure was 1.007 atm. Using the Ideal Gas Law and the measured volume of H2 gas collected to find the number of moles of H2 gas produced in the experiment.

Answer 1

number of moles of
`H_2`=4.16mol

Step-by-step explanation:

experiment data:

temperature=
`22^(\circ)C`=273+22 k=295k

pressure=1.007 atm

volume is missing so assuming volume-=100L

using ideal law relationship

ideal gas means gas which occupies negligible space and there is no interaction between the molecules of gases.

PV=nRT

put all the experimental data, we get

n=4.15 mol

number of moles of
`H_2`=4.16mol
