Question

what would be the density of n2 gas at 2atm pressure and 560 k​

Answer 1

Given - Pressure - 2 ATM

Temperature- 560 K

Find - Density of nitrogen gas.

Solution - The density of nitrogen gas can be calculated by the formula PV = nRT, where p is pressure, v is volume, n is number of moles, r is gas constant and t is temperature.

As we know, density is calculated as mass/volume, and number of moles is calculated as weight/molecular weight.

Thus, keeping the above formula in ideal gas law, new formula will be -

density - P*M /R*T.

Value of gas constant - 0.0821 ATM /K/mol

density - 2*28/(0.0821*560)

density - 1.22 g/ml.

Thus, density of N2 gas at given conditions is 1.22 g/ml.

Answer 2

Answer:

3.41 g/ml

Explanation:

Given,

P=5atm

T=500K

M=28 g/mol

We know,

ρ= RTPM

ρ= 0.0821×500

5×28

ρ=3.41g/ml
