How many moles of chloride ions are present in a 120.0 mL solution of CaCI2 that has a concentration of 0.245 M

2*6=8 and that how I got my answers

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
