I think it's D, because theoretical yield is like, the yield you'd get if 100% of the reactants formed to make product. Well that's how I think of it, but it has something to do with limiting reagents and stuff. Sorry this isn't a really detailed explanation.

Answer:
temperate marine
Explanation:
this is the only climate that has mild summers, but cold winters.
Ca(C2H3O2)2
mole of calcium acetate = 24.6 / (40.1 + (2* (2*12+3*1+2*16)))
=0.156 mol
molarity = mole / volume = 0.156 / ((250cm^3/1000)dm^3) = 0.624M
