Density at stp
WebThe abbreviation STP indicates a temperature of _____ and a pressure of _____. 0oC, 1 atm. At STP the volume of 1 mole of an ideal gas is always equal to ___ L (given to three significant figures.). This quantity is called the standard ___ volume. Blank 1: … Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data. The most used standards are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST), although these are not universally accepted standards. Other organizations have established a variety of alternative de…
