Question

A reaction at evolves of dinitrogen monoxide gas. Calculate the volume of dinitrogen monoxide gas that is collected. You can assume the pressure in the room is exactly . Be sure your answer has the correct number of significant digits.

Answer 1

The answer is "
`V = 18.8\ L`".

Step-by-step explanation:

Given:

`n= 0.788 \ mmol = 0.788 \ mol \ \text{(1 mmol is a thousandths of a mol)}\\\\R = 0.08206\ (Latm)/(Kmol)\\\\T = 17.0^(\circ)\ C = (17.0 + 273) \ K = 290 \ K\\\\ p=1\ atm\\\\V = ?`

Using idel gas law:

`PV = nRT\\\ \therefore \\\\V= (nRT)/(P)`

`V =(0.788 * 0.08206 * 290)/(1)`

`=(18.7523)/(1) \\\\\ = 18.75`
