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 13 L, pressurized to 1.2 atmat 25C. 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
