If the pressure of a 1.3 mole sample of gas is initially 1.5 atm, the volume is 1.0 L and the temperature is 25°C, what would the new volume be if moles
are increased to 2.4 and the pressure is changed to 6.0 atm and 100.0°C?

Need ! asap will mark 10 pts using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers
