# Finding molar mass of unknown element

## Homework Statement

element X reacts with oxygen to produce a pure sample of X2O3 . in an experiment, it is found that 1.0g of X produces 1.1596g of X2O3 . what is the molar mass of X?

## The Attempt at a Solution

well we can write a equation for it 4X + 3O2 ---> 2X2O3
from this we can see that 4 moles of X gives 2 moles of X2O3.
so 4*x(x is molar mass of X)g of X gives 2x+96 g of X2O3
where do we go from here?
