Areaction produced 37.5 l of oxygen gas at 307 k and 1.25 atm. how many moles of oxygen were produced? 0.538 mol, o2 1.86 mol, o2 3.22 mol, o2 7.56 mol o2

Answer : The correct option is, 1.86 moles

Solution :

using ideal gas equation,

where,

n = number of moles of gas  = ?

P = pressure of the gas = 1.25 atm

T = temperature of the gas = 307 K

R = gas constant = 0.0821 Latm/moleK

V = volume of gas = 37.5 L

Now put all the given values in the above equation, we get the moles of gas.

Therefore, the moles of oxygen produced were, 1.86 moles

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
