Title: Urgent stoichiometry , ratio of compunds
Post by: ru mi on June 09, 2020, 06:46:52 AM

Dear all,

I'm not that much in to chemistry.

If I have let's say Al2Si3O4 and Ti2Si3O4 and I have a weight of 100g of the Alumina mixture, how much does that equals to in the Titanium mixture, taken into account their mole masses?

Thanks a lot in advance.

I think both compound not existing. But if, what are your own ideas. What are the molar mass of it.
If you know this get the mol of the aluminium compound this is equal to the titanium compound.

No, it doesnt exist, it was just an example.
I only have the formula Na2Si3O7, which I have a weigh of 100g.
Now I have to weigh an amount which equals an equal amount of potassium in a K2Si3O7 compound.

Get the molar mass of each. Addition of each mass of the elements in the compound. Divide 100g by the sodium compound and multiply it with the potassium compound.
