(P1V1/T1) = (P2V2/T2)

Okay here it is. Use combined gas law. PV/T= PV/T. Standard conditions is 273 K and 1 atm. Change 23 C to K by adding 273. Substitute into the equation the atm is pressure (P) and the volume V is the ml and the T is temperature so substitute K in it. hope I helped and the aswer should be 1.56 ml

Better to the calculation yourself. I don't buy Samir's answer.
