Question

HELP
calculate the following quantity for an ideal gas:
the absolute temp. of a gas at which 4.79 * 10^ -2 occupies 135 ml at 720 torr

pls explain work thanks!

Answer 1

Use the formula: PV= nRT
P = pressure
V = volume
n = mole
R&T are both constants which you should have in your chemistry book or can look up online (ideal gas law constants)

Rearrange using algebra to solve for whatever it isyou need. For example, if you are being asked to solve for volume, you would rearrange to get:
\[V \frac{ nRT }{ P }\]
Simlarly, if you are being asked to solve for moles, you would get: \[\frac{ VP }{ RT }= n\]
