Hello everyone

1. I had calculated Molar mass of ZrO2 and it was ~ 123.2228 g/mol.

and Molar mass of (Y2O3) and it was ~ 225.8099 g/mol.

But I couldn't calculate Molar mass of ZrO2-Y2O3

2. Ho can I get the right chemical formula of Yttria doped Zirconia (ZrO2-Y2O3) with

a. 3 mol. % Y2O3

b. 8 mol. % Y2O3

c. 8.5 mol. % Y2O3
