Dinitrogen monoxide gas is collected at \( 35.0^{\circ} \mathrm{C} \) in an evacuated flask with a measured volume of 30.0 L . When all the gas has been collected, the pressure in the flask is measured to be 0.270 atm .
Calculate the mass and number of moles of dinitrogen monoxide gas that were collected. Round your answer to 3 significant digits.
mass: \( \square \) g \( \square \) 10
mole: \( \square \) mol
