Answer:

The appropriate answer is "1.96 mol".

Step-by-step explanation:

The given values are:

Volume,

V = 26.5 L

Pressure,

P = 1.7 atm

Temperature,

T = 280 K

Now,

The number of moles (n) will be:

=
(PV)/(RT)

By substituting the values, we get

=
(1.7* 26.5)/(0.0821* 280)

=
(45.05)/(22.988)

=
1.96 \ mol
