Question:

An iron contain 5% FeSO4 by mass. How many grams of iron could be obtained from 1.o lb of this ore?

Solution please:DDD

Answer:

Try and slightly loosen the clutch cable a little,see if it helps. if it dont work,you may have a cracked clutch plate.Have seen it happen before with the symptoms you mention and it was a cracked plate but i still reckon if you loosen the cable a little,it will cure it
1 lb 453.6 g. 100 g ore contains 5g so 453.6 g contains 435.6 / 100 * 5 22.7 g. at wt Fe 55.9.g/mol. mm FeSO4 151.9 g/mol. (55.9 / 151.9) * 22.7 g 8.35 g iron.
check your clutch is adjusted correctly,it could be that you have too much slack in the cable, so the clutch never fully disengages the drive from the idling engine, and is actually trying to drive you forwards.
