Question

When two moles of hydrogen and one mole of oxygen react to form two moles of water, the energy released is 484 kJ. How much does the mass of the elements decrease in this reaction? What % of the total original mass of the system does this mass change represent?

Solution

VerifiedStep 1

1 of 3We can calculate mass defect by:

$\begin{align*} m&=\frac{E}{c^2} \\ &=\frac{484 \cdot 10^3}{(3\cdot 10^8)^2} \\ &=\boxed{5,38 \cdot 10^{-12}} \end{align*}$
