What is the volume of the gas in milliliters when the pressure and temperature of the gas sample are changed to 646 mmHg and 297 K , if the amount of gas remains the same?

What is the volume of the gas in milliliters when the pressure and temperature of the gas sample are changed to 0.450 atm and 88 ∘C, if the amount of gas remains the same?

What is the volume of the gas in milliliters when the pressure and temperature of the gas sample are changed to 17.6 atm and -14 ∘C, if the amount of gas remains the same?

(765 mL) x (1.34 atm) / (646 mmHg / (760 mmHg/atm)) x (297 K / (114 + 273) K) = 926 mL

(765 mL) x (1.34 atm / 0.450 atm) x (88 + 273) K / (114 + 273) K) = 2125 mL

(765 mL) x (1.34 atm / 17.6 atm) x (-14 + 273) K / (114 + 273) K) = 39.0 mL
