Question

What is the density of nitrogen gas at 227℃ and 5.00 atm pressure?

Answer 1

The density of ideal gas can be calculated as follows:

PM = dRT

Or  

d  = PM/RT

Where;  

P =  pressure measured in atmospheres (atm), 5.00  

T =  temperature measured in kelvin (K)

Given that  

227℃ +273 = 500 K

R = the ideal gas law constant 0.0821 atm(L)mol(K)  

And  M =  now the molar mass 28.013 g/ mole

Therefore d=  5.00 *28.013 / 0.0821 *500

= 3.412 g/ L
