I fond: #1029.7ml#

Explanation:

Considering the gas as ideal we can use:
#PV=nRT#
Where:
#P=# pressure;
#V=# volume;
#n=# number of moles;
#R=# universal gas constant;
#T=# temperature.
So pasically our gas undergo a transformation from equilibrium state 1 to equilibrium state 2 where we have:
from:
#P_1V_1=nRT_1#
to:
#P_2V_2=nRT_2#

But #n# and #P# remain unchanged so we have that:
#(V_1)/T_1=nR/(P_1)#
#(V_2)/T_2=nR/(P_1)#
and so:
#(V_1)/T_1=(V_2)/T_2#

But:
#T_1=273+25=298K#
#T_2=273+50=323K#
and:
#V_2=(950*323)/298=1029.7ml#
