79.2 L of a gas are contained at STP. How many moles are present in the container?

3.54 mol

Explanation:

When at STP (Pressure of 1 atm & T of 273.16 K), one mol of any given gas occupies 22.4 liters.

With the above information in mind we can calculate the number of moles, using the factor 22.4 L/mol:

79.2 L ÷ 22.4 L/mol = 3.54 mol

There are 3.54 moles of the gas present in the container.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
