Mass numbers are used to identify different isotopes of an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an ato...
What is the mass number of potassium-39? What is the mass number of oxygen-17? What is the mass number of zinc? How many atoms of iodine are in 2.5 moles of lead iodide? What is the mass number of potassium? What is the atomic mass of nitrogen-15?
The question asks for the mass of the potassium nitrate precipitate, but potassium nitrate does NOT form a precipitate. You probably mean to ask for the mass of the copper(II) hydroxide precipitate.First, write a balanced equation:2KOH(aq) + Cu(NO3...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
