I have 0.009 moles of CaCO3 and I needed to find how many moles of CO3 are in the CaCO3. I am just making sure I am doing this correctly. 0.009 mol CaCO3 x 60.01/100.09= 0.54g CO3 0.54g CO3/ 100.09g CaCO3 = 0.005 mol CO3

Homer Hickham and his buddies launched model rockets in the late 1950's when the US was trying to get a rocket into space. If homer launches a rocket from rest and its engine delivers a constance acceleration of 8.2 m/s^2 for 5.0seconds after which the fuel is used up by t...
