Jeff and Jill go canoeing. While reaching to

feed a duck, the boat flips. Jeff and Jill blow

up their inflatable life preservers and then put

them on. As they wait for the rescue squad,

they calculate how much nitrogen is in each

life preserver. They estimate that the volume

is 17 L, pressurized to 1.3 atm at 298◦K. The air

used for inflation is 80% nitrogen by volume

and 20% oxygen by volume. Give the amount

of nitrogen gas.

Answer in units of grams.
