Another Gas Stoichiometry Problem

[Iamorton]

what if ur only given the volume with stp problem ,,how do u find the moles then reply asap?

[MrJiraiyaSage]

where did you get 65.4 g Zn??

[sendmefood]

@MrJiraiyaSage 65.4 g Zn = 1 mol of zinc (look for the atomic weight on a periodic table)

[MrJiraiyaSage]

@sendmefood ok, my bad, i didnt finish the vid, so the 65.4 is the molar mass of Zn ryt?, my teacher on honors teach us this then i start getting it and realize it was pretty easy.. , tnx anyways :D

@sendmefood

Very nice, but what if the question was rephrased to include temperature and pressure that's not at STP like find volume of H2 gas AT 288K AND 0.941 ATM?

[sendmefood]

@freezinghotter Use PV=nRT to interconvert any value you need to, where P is pressure, V is volume, n is moles of gas R is gas constant (depends on your units) and T is temperature in Kelvin. Does that help?

@sendmefood

That was what was what I was thinking earlier but was unsure. Thanks for clarifying that. We don't need the moles to liter conversion (1 mole = 22.4 liters)?
