Chapter 21.6, Problem 21.8.2PE

Interpretation Introduction

Interpretation: The positron emission of ${}_{\text{6}}^{\text{11}}\text{C}$ is given. The mass change per mole for the given ${}_{\text{6}}^{\text{11}}\text{C}$ in the nuclear reaction is to be calculated.

Concept introduction: In positron emission a proton in nucleus is converting into a neutron by emitting a positron $\left({}_{\text{1}}^{\text{0}}\text{e}\right)$ . In this process the atomic number decreased by one and the mass number remains the same

To determine: The mass change per mole of ${}^{\text{11}}\text{C}$
