Density of an ideal gas can be calculated by the formula ______?
ایک مثالی گیس کی کثافت کا حساب فارمولا ______ کے ذریعہ کیا جاسکتا ہے؟
- d=nRT
- d=PM/RT
- d= m/M RT
- d=PV/M
Explanation
The formula for calculating the density of an ideal gas is d = PM/RT, where:
- d: is the density of the gas
- P: is the pressure of the gas
- M: is the molar mass of the gas
- R: is the ideal gas constant
- T: is the temperature of the gas in Kelvin
The ideal gas law is expressed as PV = nRT, where 'n' is the number of moles.
Density (d) is mass (m) divided by volume (V), so d = m/V.
We can relate the number of moles (n) to mass (m) and molar mass (M) using n = m/M.
Substituting this into the ideal gas law, we get PV = (m/M)RT.
Rearranging the equation to solve for density (d = m/V), we get d = PM/RT.
