40.08
21
Sc
44.96
22
Ti
47.87
The Correct Answer and Explanation is :
The molar mass of titanium (Ti) is 47.87 grams per mole (g/mol). This value represents the mass of one mole of titanium atoms, which contains approximately (6.022 \times 10^{23}) atoms, known as Avogadro’s number.
Explanation:
Molar mass is a fundamental concept in chemistry, crucial for converting between the mass of a substance and the amount of substance in moles. The molar mass of an element is derived from its atomic mass, which is listed on the periodic table and reflects the average mass of an atom of that element, taking into account the distribution of isotopes in nature.
For titanium, the atomic number is 22, indicating that it has 22 protons in its nucleus. Its atomic mass of 47.87 g/mol suggests that the average mass of its isotopes, primarily titanium-48, is just under 48 g/mol. The slight discrepancy from whole numbers in atomic mass arises because atomic masses are weighted averages based on the natural abundance of the element’s isotopes.
Titanium is a transition metal known for its strength, low density, and high corrosion resistance, making it useful in various applications, including aerospace, military, and medical devices. Understanding its molar mass allows chemists to calculate how much titanium is needed for reactions or materials, facilitating the precise formulation of compounds and alloys.
When performing stoichiometric calculations in chemical reactions, knowing the molar mass of titanium allows chemists to convert grams of titanium to moles and vice versa. For example, if a chemist needed 95.5 grams of titanium for a reaction, they could calculate the number of moles by dividing the mass (95.5 g) by the molar mass (47.87 g/mol), resulting in approximately 2.00 moles of titanium. This practical application of molar mass is essential for successful laboratory work and industrial processes.
