Answer:
The volume at STP is 0,441 L (441ml)
Explanation:
We use the gas formula, which results from the combination of the Boyle, Charles and Gay-Lussac laws. According to which at a constant mass, temperature, pressure and volume vary, keeping constant PV / T. The conditions STP are 1 atm of pressure and 273K of temperature. We convert the unit Celsius into Kelvin, the volume in ml into L and the pressure in mmHg into atm:
0 ° C = 273K, 20 ° C = 273 + 20 = 293K ; 500/1000= 0,500 L
760mmHg---1 atm
720mmHg----x= (720mmHgx 1 atm)/760mmHg= 0,947 atm
P1xV1/T1= P2xV2/T2
V2=((P1xV1/T1)xT2)/P2
V2=((0,947atmx0,500L/293K)x273K)/1 atm
<em>V2= 0,441 L</em>

Hello there!
In this case, according to the given information, it turns out possible for us to realize this is a question about titration, which base solved by knowing that the HCl reacts with the NaOH in a 1:1 mole ratio, and therefore, we can write the following:
Thus, we solve for the molarity of the base, NaOH, as shown below:
