Question

What is the mass (in grams) of 5.00 L of propane vapor (C₃H₈) at STP?

Answer 1

ok

Answer 2

so G imma be honest im only in 8th grade G

Answer 3

so give me a mnute

Answer 4

min

Answer 5

idk the answer so I copied from Voca
\[PV = nRT\]
where P = pressure, V = volume, n = moles, R is the gas constant, and T is temperature

you are given STP, which implies
\[P = 1\ atm\]\[T = 273K\]
you are also given V = 5.00L from the problem

since we are using units of atm, moles, L, K then R = 0.082057

so you can plug everything in and solve for n. to go from moles to grams, simply multiply by the molar mass of propane.

This is not my work, it's Vocaloid's, I directly pulled it from: https://questioncove.com/updates/5ea31adf6f31431d9adf0c00
