ACT Question for April 23rd

Stars are essentially fusion reactors, converting hydrogen into helium, thus releasing light and heat energy.  Approximately 90% of stars are main sequence stars, which have a proportional relationship of temperature vs. luminosity.  This relationship can be observed as a function of their color, as seen in Figure 1. The lifespan and stages of a star largely depend upon its mass.  Figure 2 shows the relationship between the temperature of a main sequence star and its mass.





What would be the approximate solar mass of a blue-white star?
