Question

A reaction at 5.0°C evolves 583.mmol of dinitrogen difluoride gas. Calculate the volume of dinitrogen difluoride gas that is collected. You can assume the pressure in the room is exactly 1atm . Round your answer to 3 significant digits.

Answer 1

Answer: The volume of dinitrogen difluoride gas collected is 13.31 L.

Step-by-step explanation:

Given: Temperature =
`5.0^(o)C` = (5 + 273) K = 278 K

Moles = 583 mmol (1 mmol = 0.001 mol) = 0.583 mol

Pressure = 1 atm

Formula used to calculate volume is as follows.

PV = nRT

where,

P = pressure

V = volume

n = no. of moles

R = gas constant = 0.0821 L atm/mol K

T = temperature

Substitute the values into above formula as follows.

`PV = nRT\\1 atm * V = 0.583 * 0.0821 L atm/mol K * 278 K\\V = 13.31 L`

Thus, we can conclude that the volume of dinitrogen difluoride gas collected is 13.31 L.
