During a beta-minus decay process, a carbon-14 nucleus emits a high-energy electron (a beta-minus particle).
The mass of a carbon-14 nucleus is 2.3253 × 10-26 kg. The mass of a beta-minus particle is 9.1094 × 10-31 kg.
Calculate how many times the mass of the carbon-14 nucleus is greater than the mass of the emitted beta-minus particle.
Give your answer to two significant figures.
