I am trying to calculate the species density for a mixture of gases using the following equation:
$$P = \sum_{k=1}^n \rho_k*\frac{1}{M_k}*T$$
where:
$P$ is the pressure of the mixture, $T$ is the temperature of the mixture, $n$ is the total number of species in the mixture, $\rho_k$ is the density of species $k$, $M_k$ is the molecular weight of species $k$.
I know the values of pressure, temperature, and molecular weights of each species. However, I'm not sure how to calculate the species density from this equation. Can someone please provide a step-by-step explanation of how to rearrange and solve this equation to find the species density for each gas species in the mixture?
Thank you in advance for your help!
