How many moles of O are in Fe2O3?

For our purposes, the statement that we have 1 mole of Fe2O3 means that we have 6.02*10^23 molecules of Fe2O3.

What is the mass of 5.0 moles of Fe2O3?

2. What is the mass of 5 moles of Fe2O3 ? Smal x 159.0 1798.45g Page 2 3.

How many grams of Fe are in 50g of Fe2O3?

50.0g/x = 78.7%/100% , which rearranges algebraically to get x alone to: 50g*100%/78.7% , the percent “units” cancel out and we get 63.5324015 grams of iron(III) oxide [alternatively we could have turned the 78.7% into decimal form and solved for x in the equation 50.0/x=0.787].

How many grams are in 1.75 moles of Fe2O3?

In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt. of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe. Hence in 1.75molesFe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

What is the mass of 5 moles of?

The mass of 1 mole of any substance is equal to that substance’s molecular weight. Thus we can say that each mole of \$S{O_2} \$ weighs 64 grams. Therefore the mass of 5 moles of \$S{O_2} \$ is 320 grams.
