Jillian Choi · Answer 1

P = 1.50 atm

V = 3 L

R = 0.08205 L∙atm/mol∙K

T = 300 K

n = ?

we all this information, we can tell that we need to use ideal gas formula

PV = nRT

if we rearrange the formula for n, we get--> n = PV / RT

let's plug in the values.

n = 1.5 x 3 / (0.08205 x 300) = 0.18 moles
