Chapter 11: Stoichiometry
To verify that mass is conserved, first convert moles of reactant and product to mass by multiplying by a conversion factor—the molar mass—that relates grams to moles. moles of reactant or product × ___grams reactant or product 1 mol reactant or product = grams of reactant or product 1 mol C 3H 8 × __44.09 g C 3H 8 1 mol C 3H 8 = 44.09 g C 3H

www.mcvts.netoperational amplifiers is the very high gain achieved at the output. In general, gain is calculated as Vgain = Vout/Vin, a ratio of the output voltage to the input voltage. An op-amp amplifies the difference between one input and the other, while neither individual input is itself amplified. The output is positive if the non-inverting input is more
