HELP PLEASE...If the theoretical yield of a reaction is 332.5 g and the percent yield for the reaction is 38 percent, what's the actual yield of product in grams? \

You have to multiply the theoretical by the percent yield to get the actual yield. You perform an experiment and theoretically you get all the yield, but that's impossible as nothing is 100% efficient so you multiply the theoritcal times the efficiency ratio. 38%* 332.5= actual. It's like mpg in a car gasoline has a lot of energy, but some cars have better efficiency. Chemistry is many times never 100% effecient.

i believe it is-

d.) gravity pulled particles of dust and gas together to form planets.
