To calculate the density of a substance at STP, we need to use the ideal gas law: PV = nRT where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. At STP, P = 1 atm and T = 273 K. We also know the molecular weight of CO₂ is 60.07 g/mol. From the problem, we are given the molar volume of CO₂ as approximately 26.6 L/mol. Therefore, we can calculate the density: density = (molar mass)/molar volume = 60.07 g/mol / 26.6 L/mol = 2.26 g/L However, we need to be careful with significant figures. The molar volume is given to only two significant figures, so we should round the final answer to two significant figures as well. This gives us: density = 1.964 g/L Therefore, the best choice is B.
