The gas will occupy 120 L at STP.

We can use the Combined Gas Laws.

In 1982, chemists redefined STP as 1 bar and 0 °C (273.15 K).

p_1 = 5100 mmHg * (1 atm/760 mmHg) * (1.013 bar/1 atm) = 6.798 bar

T_1 = (29 + 273.15) K = 302.15 K

p_1V_1/T_1 = p_2V_2/T_2

V_2 = V_1 * p_1/p_2 * T_2/T_1

= 20.1 L * (6.798 bar/1 bar) * (273.15 K/302.15 K) = 120 L
