Suppose you have two samples that are equal in weight, 21.3 g Ti and 21.3 g Cr2O3 .
Calculate the number of moles of each substance.
For Ti I got .444 and for Cr2O3 I can't get the answer for some reason.
I did 151.989/21.3 and got 7.13 but it shows up as incorrect, but I did the same steps as I solved for Ti. Could someone help where I went wrong?
For Ti I did 21.3/47.9 and got .444

Nevermind I realize where I went wrong ): Careless mistake haha
No, you didn't do the same step.
mols = grams/molar mass
mols = grams/molar mass
