What is the volume of 1.2 moles of oxygen gas (o2) at standard temperature and pressure (stp)?

 The volume of 1.2 moles of oxygen gas () at standard temperature and pressure (STP) is 26.9 Liters

Explanation:

Using ideal gas equation:  

PV = nRT

At standard conditions of temperature and pressure:

P= pressure = 1 atm

T = temperature = 273 K

V= volume = ?

Given: n = no of moles = 1.2

R= gas constant =0.0821 Latm\molK

Putting in the values we get:

The volume of 1.2 moles of oxygen gas () at standard temperature and pressure (STP) is 26.9 Liters

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
