Question

A gas occupies 100 cm3 at S.T.P. What do you mean by this statement?​

Answer 1

Answer:

The term 'S.T.P.' means the standard temperature and pressure.

• The standard temperature = 273K OR 0°C
• The standard pressure is 1 atmosphere OR 76 cm of Hg OR 760mm of Hg.

So, the statement 'A gas occupies 100 cm3 at S.T.P' means that

A gas at 0°C occupies 100cm³ when under 1 atmosphere of pressure.
