I NEED HELP ASAP PLSS ANYONE. {50 POINTS}

Look for the conversion factor(tile) that contains the units "mol Fe2O3" and "159.70g Fe2O3".
Drag the tile containing this factor down to the green strip at the bottom. Notice the grams of Fe2O3 cancel.
Now look for the conversion factor(tile) with "mol of Fe" and "mol of Fe2O3" and drag it down to the green strip. If the moles of Fe2O3 don't cancel, click flip the tile until the moles of Fe2O3 cancel.
Finally find conversion factor(tile) with " 55.85 g Fe" and "1 mole of Fe". If the moles of Fe don't cancel, click flip the tile until the moles of Fe cancel.
Turn on Show units and Show numerical result.


How many moles of iron (Fe) can be obtained from 3.80g iron(III) oxide(Fe2O3) reacting with excess carbon monoxide (CO)?


What is the mole ratio of Fe to Fe2O3 ?

Answer:

Ok this is my answer for you, I don't know if it will help but I hope it will

Step-by-step explanation:

The balance chemical equation is

Fe2O3+3CO=2Fe+3CO2

Convert the 3.80g of Fe2CO3 to moles using the equation

Moles=mass/molar mass

Molar mass of Fe2O3=159.69g/mol

Moles of Fe2O3=3.80/159.69= 0.0238mol

The molar ratio of Fe2O3 to Fe is 1:2

The 1=0.0238mol

2 = x moles of Fe

Cross multiplying gives

x=0.0476mol of Fe

Convert moles to mass using the same equation solving for mass gives

Mass=moles*molar mass

Molar mass of Fe=55.845g/mol

Mass of Fe=0.047*55.845=2.66grams
