A 5.000 L tank at 1(13 C is lled with 11.2 g of carbon monoxide gas and 4.45 g of dinitrogen monoxide gas. You can
assume both gases behave as ideal gases under these conditions.

After the ice is melted, its temperature needs to be raised from its melting temperature (0 "(3) to 69.2 0C, which is a change of

A sample of an unknown compound is vaporized at 209. C. The gas produced has a volume of1510. mL at a pressure

EXPLANATION
Heat is needed for two reasons in this problem:
1
Atmospheric pressure:
The third force on the mercury is the force exerted on the mercury in the Jtube by the atmosphere. When the end of the
Jtube is openIr air from the atmosphere will enter it and push clown on the mercury. That will make the mercury ow

There are 3 signicant digits in 1.25 g and 4 in 1510. mL. That means your calculated value For .1) has 3 signicant
digits. But keep two extra for now, and only round the nal answer to the correct number
It's the equation for p that will let you solve this problem.
FirstIr you'll need to convert the temperature of the sulfur tetrauoride gas to absolute temperature:
