Use PV = nRT
Remember P is in atm and T in Kelvin. Solve for n = number of moles.
Then moles = grams/molar mass. Solve for grams. For b), remember there are 6.022 x 10^23 molecules in a mole.
Consider a 980-mL container at 133 °C in which the pressure of nitrogen oxide is 0.394x106 Pa.
a) What mass of nitrogen oxide (in g) is present in this container?
b) How many molecules is this?
(a)----g
(b)-----molecules
