What if i have more than one acid and i want this to react with methanol. How should i calculate the amount methanol that i need to use?

How do you know there is 3 moles of CO per mole of Fe2O3

I'm not sure if you balance the equation right or my teacher is dumb but Fe2O3+CO --> 2Fe + 2CO2
There are
A. 2Fe (iron)
O3+0=4 (oxygen)
C=1 (carbon)
=total of 7.
B. 2Fe (iron)
2O*2=4 (oxygen)
C=1 (carbon)
=total 7.

Didn’t understand the ending. You just rushed everything 👎

Sorry but I have to say that u have done terrible mistake:
The answer should be 1.0588 cuz u canceled 1 mole of CO therefore the remaining is 2 mole of CO not 3
Thank you kind person
If i have mistake correct me :)

Someone needs to do one of these where you are given a target mass of product like for example .10 grams of copper. And use this target mass to determine how much reactant is needed to produce this mass. The equation is 2Al+3CuCl2--->2AlCl3+3Cu. We need to know how much Aluminum and CuCl2 is needed to produce a product of .10 grams of copper.

I dont understand the last operation, what do you do in the minute 3:25? (More or less)

A. Calculate the mass of CO needed to react completely with 50.0 g of Fe2O3 .

B. Calculate the mass of iron produced when 125 g of CO reacts completely.

C. Calculate the mass of CO2 produced when 75.0 g of iron is produced.

How do i do this with Moles instead of gram Though?

Thank you so much, my anxiety is literally cured!!!

Why is it that in most cases, the amounts of reactants and products are indicated in grams
instead of the number for moles??

you didnt say what calculation you did to get the grams of co?
