Work Step by Step
Use the molar mass of iron in order to convert moles into grams.
The volume of one mole of gas at STP is 22.4 L. Use this as a conversion factor. Also use the molar mass of carbon monoxide the obtain the number of grams of CO.
Use Avogadro's number to convert molecules into moles. Then use the molar mass of glucose to convert moles into grams.
Use the molar mass of ammonium phosphate in order to convert grams into moles.
