Question

A gas sample has a temperature of 19 °C with an unknown volume. The

same gas has a volume of 464 mL when the temperature is 90. °C, with no
change in the pressure or amount of gas.

Answer 1

Answer: 373 mL

Step-by-step explanation:

Since there is no change in pressure, the formula: V / T = V / T can be used.

However, you must first convert the temperatures to Kelvin by adding 273 to them:

(19 + 273) = 292K and (90 + 273) = 363K.

Now, plug in: V / 292 = 464 / 363 → V = 373 mL :)
