At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 L. The molar mass of nitrogen (N2) is 28 g/mol. To find the mass of nitrogen needed to fill an 855 L tank, first calculate the number of moles: 855 L / 22.4 L/mol = 38.17 moles. Then, multiply by the molar mass: 38.17 moles * 28 g/mol = 1068.76 g, which is approximately 1.07 kg.
