help me please..thank you

Extracted text: (a) What is the effect of the following on the volume of 1 mol of an ideal gas? (i) The temperature changes from 305K to 32 °C, and the pressure changes from 2 atm to 101 kPa? (ii) Both of the pressure and temperature decrease to one-fourth of its initial values. (b) Hydrogen fluoride is produced from fluorspar, the commercial name for the mineral fluorite (CaF2). The mineral is widely distributed in workable deposits throughout the world, particularly in China, Mexico, Southern Africa and Russia. When 20.0 g of fluorite (CaF,) reacts with excess sulfuric, hydrogen fluoride gas is collected at 1 bar and 289.65 K. Solid calcium sulfate is the other product. Estimate the gas temperature required to store the gas in a 10.0 L container at 1.17 bar.
