If a 0.10 m solution of a colored substance has a maximum absorbance at 500 nm and an absorbance of 0.26 m at this wavelength, what will be the measured absorbance of a 0.20 m solution at 500 nm?

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.
