Chapter 20.2, Problem 3CP

Interpretation Introduction

Interpretation:

The change in mass in kilogram for the following reaction is to be calculated.

Concept introduction:

The relation in between the energy $\left(\Delta E\right)$

and mass $\left(\Delta m\right)$

was given by Einstein as follows:

$\Delta E=\Delta m{c}^2$

Here, $c$ is the speed of light.

Since, $\text{1 J}\text{=}{\text{1 kg m}}^{\text{2}}{s}^{-2}$, conversion factor is as: $\frac{{\text{1 kg m}}^{\text{2}}{s}^{-2}}{1\text{Joule}}$

$1\text{ mol=}6.0221418\times {10}^{23}$

(Avogadro’s number)
