Question

If the volume of 2.46 x 1021 molecules of HBr(g) at 46. °C and 1.36 atm is 86.7 mL, then what is the volume of 2.46 x 1021 molecules of CO2(g) at 46. °C and 1.36 atm?

Answer 1

Question:

If the volume of 2.46 x 1021 molecules of HBr(g) at 46. °C and 1.36 atm

is 86.7 mL, then what is the volume of 2.46 x 1021 molecules of CO2(g)

at 46. °C and 1.36 atm?

Solution:

The volume of CO2 will be the same, because volume of gas depends from number of moles, temperature, pressure, but not depends from exact gas. Molar mass og gas is not important.

So in the same conditions volume of the CO2 will 86.7 mL.

Answer: 86.7 mL.
