Consider the image below depicting an ideal gas contained within a 4.5 L 4.5 L cylinder under a constant force. If 3.0 × 10 − 3 moles 3.0×10−3 moles of gas are occupying the cylinder and the temperature of the gas is 350 K 350 K, determine the mass of the weight on the cylinder. Assume the top of the cylinder has an area of 1.0 m 2 1.0 m2, and atmospheric pressure can be ignored.
