can i get solution for all please. thank you

A sample of argon has a volume of 1.20L at STP. If the temperature is increased to 23.0C and the pressure is lowered to 0.800atm, what will the new volume be, in L ? 45.0L of an ideal gas at 288K and 3.50atm are heated to 373K with a new pressure of 4.70atm. What is the new volume (in L )? A balloon is filled to a volume of 1.75L with 3.50 moles of gas at 25 C. With pressure and temperature held constant, what will be the volume of the balloon if 0.80 moles of gas are released? A weather balloon calibrated at 0.00C to have a volume of 20.0L has what volume in L at 14.4C assuming pressure is held constant
