A cylinder with 24 = 13.13 cm inner diameter and an hmax = 11.81 cm height is placed on a heating plate. A weighted circular disc fits snugly into the cyli i i 1 : ylinder, creating a gas-tight seal; the combined mass of the disc and the weights it supports is 17.22 kg. o Schimpf, Erin - erschim@ilsta edu @theexpertta com - tracking 1d: 5I76-95-CB-45-9A29-43551.

How much helium gas, in moles, is in the cylinder if it has a temperature of 24.1C? (Assume that the gas in the cylinder approximates an ideal gas.) M | & & 50% Part (b) Suppose an additional mass of 4.11 kg is placed on the disc, but at the same mE@,?o heating plate is used to heat the gas in the cylinder. If the height of the disc above the cylinder bottom is now 76.8% of hmax, then what is the change in the temperature, in degrees Celsius, of the gas? i e Grade Summary T e Potential 100% J_O_D [ ey ~ [ A iln__ HJ / Suhmiccinne
