What pressure is required to achieve a CO2 concentration of 4.80×10^−2 M at 20∘C?

Answer 1

Favorite Answer

we know

PV = nRT

P = CRT

P - pressure

C - Concentration = number of moles / volume = n / v

R = gas constant = 0.0821 lit.atm/K.mol

T = temperature = 200c + 273 K =293K

P = 4.8 * 10-2 *0.0821 * 293

    = 1.154 atm

Answer 2

P = nRT / V = (n/V) RT = (4.80×10^−2 mol/L) x (0.082057366 L atm/K mol) x

(20 + 273) K = 1.15 atm
