What is the approximate mass of one mole of chromium?

• A. 12 g
• B. 24 g
• C. 52 g
• D. 6.02 x 10^23 g

Answer: (C)

The approximate mass of one mole of chromium is indeed around 52 grams. This value corresponds to the molar mass of chromium, which is found on the periodic table and is a critical concept in analytical chemistry. Molar mass is defined as the mass of one mole of a substance, expressed in grams per mole (g/mol). For chromium, its atomic weight is approximately 51.996 grams per mole. When we round this to a whole number for convenience, it is typically referred to as 52 grams per mole. This means that one mole of chromium atoms has a mass of about 52 grams. Understanding the molar mass is essential for stoichiometric calculations, where the relationship between the mass of a substance and the number of moles is necessary to determine the amounts of reactants and products in chemical reactions. This insight reinforces the importance of knowing molar masses accurately in various analytical applications.
