WebThe molar mass of water (H2O) can be determined by adding up the atomic masses of each element present in the compound. Water is composed of two hydrogen atoms (H) and one oxygen atom (O). The atomic mass of hydrogen is 1.008 amu (atomic mass units). The atomic mass of oxygen is 16.00 amu. Therefore, the total mass of water is: Chromium is the fourth transition metal found on the periodic table, and has an electron configuration of [Ar] 3d 4s . It is also the first element in the periodic table whose ground-state electron configuration violates the Aufbau principle. This occurs again later in the periodic table with other elements and their electron configurations, such as copper, niobium, and molybdenum. This occurs because electrons in the same orbital repel each other due to their like charges. In t…
