Question

গ্যাসের ঘনত্ব মাপতে ব্যবহৃত হয় (Density of a gas can be determined using)

Arrhenius equation

Perfect gas equation

Einstein equation

Faraday equation

ANSWER : 2

Descrption

Out of the given options, the equation used to determine the density of a gas is:Perfect gas equationExplanation:<ul><li>The Arrhenius equation relates the rate constant of a chemical reaction to temperature.</li><li>The Einstein equation describes the relationship between mass, energy, and the speed of light.</li><li>The Faraday equation relates the amount of electric current to the amount of chemical change.</li></ul>Perfect gas equation (PV = nRT) relates pressure (P), volume (V), number of moles (n), gas constant (R), and temperature (T). By rearranging the equation, you can derive the ideal gas density formula:density (ρ) = n/V = (P / RT)Therefore, the perfect gas equation allows you to calculate the density of a gas based on its pressure, temperature, and the universal gas constant
