To calculate the number of moles from grams, you must divide by the substance's molar mass


A piece of iron weighing 85.65 g was burned in air The mass of the iron oxide produced was 118.37 g use the molar mass of iron to convert the mass of iron used to moles?

okay, it does not tell us how much iron reacted with oxygen, so we assume that iron reacted completely. just convert grams iron used into moles. 85.65g Fe/55.85g Fe X 1 mole Fe = 1.534 moles Fe btw the empirical formula you should get is Fe3O4

Are 3 moles of gold heavier than 10 moles of iron?

Let's see. 3 moles gold (197.0 grams/1 mole Au) = 591 grams of gold ----------------------------- 10 mole iron (55.85 grams/1 mole Fe) = 558.5 grams of iron ----------------------------- So, 3 moles of gold has more mass that 10 moles of iron. (heavier)




What is the mass of 1.4 moles of Fe2O3?

The molar mass of Fe2O3 is 55.845 (molar mass of iron)*2+16(molar mass of oxygen)*3, which comes out to be 159.69 grams per mole. Multiply that by the number of moles, and the answer is 223.57 grams.
