At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 liters. The molar mass of nitric oxide (NO) is approximately 14.01 (for N) + 16.00 (for O) = 30.01 g/mol. For 10.0 g of NO, the number of moles is 10.0 g / 30.01 g/mol = 0.333 moles. The volume occupied by 0.333 moles of NO at STP is 0.333 moles * 22.4 L/mole = 7.46 L.
