Which subatomic particle has a positive charge and is located in the nucleus with a mass of 1 amu?

Explanation:
In atoms, the nucleus hosts protons and neutrons; the particle with a positive charge and a mass around 1 amu that resides in the nucleus is the proton. Protons carry positive charge and contribute most of the atom’s mass, with a mass close to 1 amu (approximately 1.007 amu). Neutrons are also in the nucleus but have no net charge. Electrons orbit the nucleus and are far lighter and negatively charged. Quarks are the smaller constituents inside protons and neutrons, not standalone particles in the nucleus with a defined 1 amu mass. So the described particle is the proton.
