21.5 ml is the molar volume of gas for this trial.
Volume=21.1 ml
moles=9.64x10^-4
no. of moles= given volume/22.4 L
V=n×22.4 L
V=9.64x10^-4×22.4×1000 ml
V=21.5 ml
The equation relates the volume and number of moles of a gas. V is for volume, n is for the number of moles, and V is for molar volume. A proportionality constant known as the molar volume describes the volume of one mole of any gas at a specific temperature and pressure.
It is helpful to establish a standard temperature and pressure that may be used as reference conditions when comparing various gases since the volume and, consequently, the density of a gas rely on those two factors. The definitions of standard temperature and pressure are 0°C and 1 atm, respectively. Standard temperature and pressure are referred to as STP together.
