**2.1.5. Baryons in Stars and Remnants**

With the above numbers the mean mass densities in our three classes of stars and their associated remnants are

10^{11} *h*^{2} *M*_{} Mpc^{-3}. Here
and below the upper (lower) errors are obtained by taking all
errors in each step to maximize (minimize) the result. In this
sense the error ranges are conservative. The numbers in
equations (10)-(12) depend through the *M/L* calculation on
age estimates, and hence depend on the Hubble
constant *h* and other cosmological parameters in a complicated
way. If dynamics were used to estimate *M/L* the estimates of
would not depend on *h*,
but in that case *h* 0.7
would be needed for dynamics to agree with the synthesis calculations.
Either way, consistency holds for *h* 0.7 in a low density universe.
