1.630g of iron ore detemine moles of Fe2
David, Notice there are two moles of iron per mole mole of Fe2O3; find the number of moles of Fe2O3 and double that number! Moles Fe 2 x moles Fe2O3 2 * (1.630 g/159.69 g/mole) 0.02041 moles (four sig figs) Hope that helped!
I'm assuming front brake but it doesn't really matter as both are hydraulic. The master cylinder is usually the main cause of pressure degradation in brake systems. A rebuild seems in order.
there's a scarcity of CO given which you like 3 moles of CO for each mole of Fe2O3. you like 0.756 moles of CO. given which you have purely 0.554 moles of CO, enable's do it this way: a million mole of Fe2CO3 with 3 moles CO yields 2 moles of Fe. 0,252 moles Fe2CO3 with 0.756 moles C0 would yield 0.504 moles Fe. with the aid of dearth of CO, you will get purely 0.554 / 0.756 x 0.504 moles Fe
bleed the front brake lines. Good luck and ride safe.
