For a distance d=14 Mpc, find the blue luminosity of NGC 7331 from its apparent total magnitude. Show that ℳ(HI) / LB ≈0.2 in solar units. Assuming the galaxies to have the same B-V color as the Sun, use Table 4.1 to show that M 31 has about the same ℳ(HI) / LB as NGC 7331, and compute this ratio for the Magellanic Clouds. On the basis of Problem 2.8, assume that ℳ / L ≥2 for the stars in NGC 7331 ; show that, even if we include the molecular gas, the mass in its stars is at least five times lar
