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
Explanation:
Given parameters:
Initial volume V1 = 200cm³
Initial temperature = 60°C
Final temperature = 120°C
Unknown:
Final volume = ?
Solution:
According to Charles law, at constant pressure, the volume of a given mass of gas is directly proportional to temperature.
mathematically;

1 and 2 are the initial and final states
V is the volume and T is the temperature
convert the temperature to kelvin
T1 = 60 + 273 = 333K
T2 = 120 + 273 = 393K
Input the parameters;

final volume is 236cm³
