Question

If 21 mL of gas are subjected to a temperature change from 10.0^circ C to 120^circ C and a pressure change from 1.0 atm to 15 atm, the new volume is: (Be sure to use the correct number of significant figures.) 440 mL 1.0 mL 0.53 mL 1.9 mL

Answer 1

To solve this problem, we can use the combined gas law, which relates the pressure, volume, and temperature of a gas:

where:-

and

are the initial and final pressures,-

and

are the initial and final volumes,-

and

are the initial and final temperatures in Kelvin.First, convert the temperatures from Celsius to Kelvin:

Now, plug in the known values into the combined gas law equation:

Solve for

:

Calculate

:

Considering significant figures, the initial volume (21 mL) has two significant figures, so the final answer should also have two significant figures:

Therefore, the new volume is approximately 1.9 mL.
