0.46 L is the new volume of the balloon

Explanation:

When the moles of a gas remain constant we have this situation for these conditions

P1. V1 / T1 = P2. V2 / T2

First of all we convert the mmHg to atm

1050 mmHg. 1 atm / 760 mmHg = 1.38 atm

We also need absolute T°C

T° K = T°C + 273 → 23.6°C + 273 = 296.6 K

STP → 1 atm = P; 273 K = T

Now we can replace the values:

1.38 atm. 036 L / 296.6K = 1 atm. V2 / 273K

(1.38 atm. 036 L / 296.6K). 273 K = 1 atm. V2

(1.38 atm. 036 L / 296.6K). 273K) / 1 atm = V2 → 0.46 L
