A scientist uses the increase in dry mass to estimate the rate of photosynthesis in 15 bean seedlings.
The combined dry mass of the seedlings at the start is 2.10 g. After 8 days, their combined dry mass is 3.54 g.
Calculate the mean rate of increase in dry mass per seedling per day.
Give your answer in mg\text{mg}mg per seedling per day.
