Loschmidt constant

The Loschmidt constant is a scientific figure that tells us how many gas molecules are present in a specific volume of space at standard conditions (like normal temperature and pressure). Specifically, it states there are about 2.69 x 10^25 molecules in one cubic meter of gas. This number helps scientists understand and calculate gas behavior, such as pressure and temperature, by providing a measure of molecule density in a given volume. It’s fundamental in fields like physics and chemistry for modeling how gases behave at the microscopic level.
