To solve this you need molar weights for CaO&CaCO3 Mw CaO=56.077g/mol and Mw CaCO3=100.086g/mol Using stochiometry: 500.0gCaO * (1mol CaO/56.077gCaO) * (1mol CaCO3/1mol CaO) * (100.086g CaCO3/1mol...

3. STOCHIOMETRY HELP!!! help me solve this problem?

I'll try to help you f(x)=1/(x^2+(1/x^2)) this expression (1/x^2) equal (1^2/x^2)=(1/x)^2=x^-2 then the function would be like f(x)=1/(x^2+x^-2) and here if we take x^-2 as a common factor then f(...
