The middle one.
CaBr2 + 2AgNO3 --> 2AgBr + Ca(NO3)2
mols CaBr2 = g/molar mass
Using the coefficients in the balanced equation, convert mols CaBr2 to mols AgNO3.
Now convert mols AgNO3 to g. g = mols x molar mass.
I have to write the equation for the following and I am not figuring it out.I was out with flu and so lost...please help.
