**1. The problem statement, all variables and given/know**

Given: Nitrogen: 2g, it takes 820cm

^{3}at 2 atm pressure. What is the temperature (T) of gas? Answer: 280K

## Homework Equations

P*V = n*R*T

P - pressure

V - velocity

n - moles?

R - constant, 0.0820 ? when I use liters, atm

T - temperature in kelvins

## The Attempt at a Solution

At first I calculate moles. 2g/14 - 0,142 moles

Then use equation. 2atm * 0,82L = 0,142moles*0.082*T

And I get a totally different answer for T = 149K
