rho=(etaxxM)/V

Explanation:

Knowing the fact that color(red)("no. of mole" (eta)=("mass"(m))/("Molar mass"(M)), just rearrange the formula to find the mass; so that,
m=etaxxM

The standard formula of "density"(rho)=("mass"(m))/("Volume"(V)). If eta is given in the problem, the variable m can be substituted with etaxxM as reflected in the relationship above. This way, the density formula through the use of eta will be presented as;
rho=(etaxxM)/V
