What does it mean when a problem says "give the values for STP"?

STP stands for "standard temperature and pressure."

Standard temperature is zero degrees C or 273 Kelvin. Standard pressure is 760 mm Hg or 1 atmosphere. So you would want to answer 273 Kelvin and 1 atmosphere pressure.

Just to be picky I would answer

273 kelvin and 1 atmosphere pressure.

Because the word for a unit has a lower case first letter, even if it is named after someone.

How about that? I learn something every day. That will teach me to always write 273 K and 0oC.

But I didn't leave a space between the degree sign and C.

When a problem asks you to "give the values for STP," it is referring to the conditions of Standard Temperature and Pressure (STP). STP is a standard set of conditions used for comparing and measuring the properties of gases. It is commonly defined as a temperature of 0 degrees Celsius (273.15 Kelvin) and a pressure of 1 atmosphere (101.325 kilopascals or 760 mmHg).

To provide the values for STP, you would simply state that the temperature is 0 degrees Celsius or 273.15 Kelvin and the pressure is 1 atmosphere. If the problem requires calculations or conversions involving STP, you would need to use these specific values as a reference.
