What volume will 0.75 moles of oxygen gas occupy at stp?

Volume occupied by oxygen gas at STP is 16.78 liters.

Explanation:

At STP, value of pressure ,P = 1atm

At STP, value of Temperature ,T =  273 K

Number moles of oxygen gas ,n= 0.75 moles

According to ideal gas equation :

PV=nRT, R = Universal Gas constant = 0.0820 L atm/mol K

Volume occupied by oxygen gas at STP is 16.78 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.
