Answer: The new volume at STP is 1125.43 mL.
Step-by-step explanation:
STP conditions:
Pressure of the gas is 760 mmHg and temperature of the gas is 273 K
To calculate the volume when temperature and pressure are changed, we use the equation given by combined gas law. The equation follows:

where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
Conversion factor: 1 cm = 10 mm
![P_1=175cmHg=1750mmHg\\V_1=555mL\\T_1=37^oC=[37+273]=310K\\P_2=760mmHg\\V_2=?mL\\T_2=273K](https://img.qammunity.org/2020/formulas/chemistry/college/kouobdrb2nk8zrbhewoh8w4ehhoypdp19b.png)
Putting values in above equation, we get:

Hence, the new volume at STP is 1125.43 mL.
