The density of nitric oxide (NO) gas at 0.866 atm and 46.2 degrees celcius is ____ g/L
Artyom0805 [142]

Answer:

 d = 0.992 g/L

Explanation:

Data Given:

Pressure of nitric oxide (NO) = 0.866 atm

Temperature of a gas = 46.2° C

Convert the temperature to kelvin = 46.2° C + 273  

temperature in kelvin = 319.2 K

density of nitric oxide (NO) = ?

Solution:

Density of a gas can be calculated by

                       d = PM /RT

Where

d = density

P = Pressure

M = molar mass of gas

R = ideal gas constant  = 0.0821 L atm mol⁻¹ K⁻¹

T = temperature

So,

Molar mass of NO = 30 g/mol

Put values in the formula:

                        d = PM /RT

           d = 0.866 atm × 30 g/mol / 0.0821 L atm mol⁻¹ K⁻¹ × 319.2 K

           d = 25.98 atm. g/mol / 26.2 L atm mol⁻¹

           d = 0.992 g/L
