The correct Answer is:
To solve the question, "The mass of one mole of a substance in grams is called its ….A ……. Here A refers to", we need to identify the term that describes the mass of one mole of a substance. ### Step-by-Step Solution: 1. **Understanding the Concept**: - The question states that we are looking for a term that describes the mass of one mole of a substance measured in grams. 2. **Defining Molar Mass**: - The term that describes the mass of one mole of a substance is known as "molar mass". Molar mass is defined as the mass of one mole of a substance (in grams) and is usually expressed in grams per mole (g/mol). 3. **Example for Clarity**: - For instance, if we take sodium (Na), its molar mass is approximately 23 grams per mole. This means that one mole of sodium weighs 23 grams. 4. **Conclusion**: - Therefore, the answer to the question is that the mass of one mole of a substance in grams is called its **molar mass**. 5. **Identifying A**: - In this context, A refers to **molar mass**. ### Final Answer: The mass of one mole of a substance in grams is called its **molar mass**. Here, A refers to **molar mass**. ---
