Question

determine the number of moles of a gas which occupies 39.0 mL at 27 degrees celsius if the pressure is 107 kPa?

Answer 1

Use ideal gas law formula: \(PV=nRT\)
P = pressure [atm]
V = volume [L]
n = mol
R = gas constant
T = temperature [K]

remember from algebra, rearrange and solve for "n"
[HINT: that means divide R&T]

Answer 2

ok thank you so much that is just what i needed :)
