Using the equation below, how many liters of water can be made from 7.6 L of oxygen gas at STP?

V = 15.2 L

Explanation:

STP means that T = 273 K and P = 1 atm.

We use the PV=nRT equation to convert the given liters of oxygen to moles:

Now we convert O₂ moles to H₂O moles, using the stoichiometric coefficients of the equation:

Finally we use the PV=nRT equation once again to convert 0.68 moles of H₂O to liters:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
