If the mass of a proton is 2.53 x 10^-37 gram, what is the mass of 1,000 protons
Dmitrij [34]
We can solve this problem by the rule of three.

1000 protons=10³ protons

1 proton------------------2.53*10⁻³⁷g
10³ protons----------   x

x=(10³ protons  *   2.53*10⁻³⁷) / 1 proton=2.53*10⁻³⁷⁺³ protons=
=2.53*10⁻³⁴ protons

answer: 2.53*10⁻³⁴ protons
