Final answer:
Using the standard molar volume of 22.4 L at STP, 11.90 moles of Co would occupy 266.56 liters, which does not match the given multiple-choice options.
Step-by-step explanation:
To calculate the volume in liters of 11.90 moles of Co (cobalt) at standard temperature and pressure (STP), we use the concept of standard molar volume. This concept states that one mole of an ideal gas occupies 22.4 liters at STP - a condition defined as 0°C (273 K) and 1 atmosphere of pressure. To find the volume that 11.90 moles occupy, we simply multiply the number of moles by the molar volume.
Volume = moles × molar volume at STP
Volume = 11.90 moles × 22.4 L/mole
Thus, the volume for 11.90 moles of gas at STP is:
Volume = 11.90 × 22.4 L = 266.56 L
This value does not match any of the multiple-choice options provided in the question, which suggests there may have been a miscalculation or a typo in the given options. Under correct calculations, the volume should be 266.56 liters.
