A neutron, I'm technically not really guessing but I'm kind of guessing because there's only 3 particles in a atom, a proton, neutron and electron, for only protons and neutrons live in the nucleus so be deduction would be neutrons.
Answer:
~1.417M
Explanation:
Molarity=(number of moles of solute)/(litres of solution)
In this case, we need to find moles of potassium bromide.
Mass=25.3g
Molar mass= 119g/mol
moles=(mass/molar mass)
=(25.3)/(119)
=0.2126moles of potassium bromide
Molarity=(0.2126)/(150/1000)
~1.417M
Hope this helps:)
