PV = nRT
P in kPa.
V in L
T in kelvin
R = 8.314
Solve for n, then
n = grams/atomic mass. You have n and atomic mass, solve for grams.
Low-pressure sodium lamps have a sodium vapor pressure of 0.7 Pa at 260 °C. How many micrograms of Na must evaporate at 260 °C to yield a pressure of 0.7 Pa in a 27-mL bulb?
