Hi all

I somehow forgot the basics of m, n, and M conversions!

In x + y = xy

We have a molar ratio of x:y = 5. I know the molar masses of both compounds.

If we have 100g of xy - how to get the masses of x and y separately?

### Re: calculate mass from molar ratio

Basic is n= m/M

If you know molar Mass M of XY then you can calculate n the moles of XY for a given mass m of 100 g and the equation reqires each component also 1 then m of X and Y also known.

If ratio X/Y = 5 then X = 5*Y but not necessary.
