Solve without using a calculator. on a cold day near the ocean, it was found that 8 g of an unknown gas occupies a volume that is a little less than 6 l. based on this information, what is the most likely identity of the unknown gas?

Assuming that the gas acts like an ideal gas so that the molar volume is Vm = 22.4 L / moles, we can calculate for the number of moles.

number of moles = 6 L / (22.4 L / mol) = 0.2679 moles

So the molar mass of this gas is:

molar mass = 8 g / 0.2679 moles = 29.9 g/mol

The value is around 32 g/mol which is the molar mass of oxygen. Therefore the answer is:

O2

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
