Question

calculate no. of moles in 350 cm3 of co2 at 273 k and 2 atom pressure

Answer 1

Here in this, we can apply the Ideal Gas equation..!!

Pressure(P) = 2 atm

Volume(V) = 350 cubic cm = 0.35 lit.

Temperature(T) = 273K

Gas Constant(R) = 0.0821 litre•atm/K•mole

No. of moles(n) = [?]

By applying Ideal gas equation,

PV = nRT

Therefore, n = PV / RT

So, n = (2×0.35) / (0.0821 × 273)

So, n = 0.03123 moles
