Question

1. the mass of a neutron is about 1.67493×10⁻²⁷ kg. the mass of a proton is about 1.67262×10⁻²⁷ kg. explain which is heavier.

Explanation:

Step1: Compare the coefficients

The coefficient of the mass of the neutron is $1.67493$ and for the proton is $1.67262$. Since $1.67493>1.67262$ and the exponents of 10 are the same ($10^{- 27}$ for both), the mass with the larger coefficient is heavier.

Answer:

The neutron is heavier.
